    Let’s analyze each statement one by one:

    1. East-West Corridor under Golden Quadrilateral Project connects Dibrugarh and Surat: The East-West Corridor under the Golden Quadrilateral project connects Silchar in Assam to Porbandar in Gujarat, not Dibrugarh to Surat. So, this statement is incorrect.
    2. Trilateral Highway connects Moreh in Manipur and Chiang Mai in Thailand via Myanmar: The Trilateral Highway is indeed designed to connect Moreh in Manipur, India, to Mae Sot in Thailand, via Myanmar. However, the endpoint in Thailand is Mae Sot, not Chiang Mai. So, this statement is partially correct but inaccurate in details.
    3. Bangladesh-China-India-Myanmar Economic Corridor connects Varanasi in Uttar Pradesh with Kunming in China: The BCIM (Bangladesh-China-India-Myanmar) Economic Corridor is planned to connect Kolkata in India with Kunming in China, not Varanasi. So, this statement is incorrect.

    None of the statements is completely correct. Thus, the correct answer is: None

    The Llanos (pronounced YAH-nos) are vast tropical grasslands located in northern South America, primarily in Venezuela and Colombia, between the Andes Mountains to the west and the Guiana Highlands to the east. These plains form part of the Orinoco River basin and are characterized by their flat terrain and unique ecological features.

    Key Characteristics of the Llanos:

    1. Geography:
      • Spanning over 220,000 square miles (570,000 km²), the Llanos cover a significant portion of the Orinoco River drainage basin.
      • They are bordered by the Andes Mountains to the west and the Orinoco River to the north and east.
    2. Climate:
      • The Llanos have a tropical savanna climate with distinct wet and dry seasons.
        • Wet season (May to October): Intense rainfall leads to seasonal flooding, turning the plains into wetlands.
        • Dry season (November to April): The landscape becomes arid and dry, often leading to grass fires.
    3. Vegetation and Wildlife:
      • Vegetation consists mainly of grasses, shrubs, and scattered trees, adapting to the seasonal flooding and fires.
      • The Llanos are rich in biodiversity, with species like:
        • Capybaras, giant anteaters, jaguars, and anacondas.
        • Birds such as scarlet ibis, herons, and hawks.
        • Aquatic species like river dolphins, caimans, and various fish during the wet season.
    4. Economic Activities:
      • Cattle ranching: The Llanos have long been used for extensive cattle grazing, a practice introduced by Spanish colonists.
      • Oil and Gas: Significant oil reserves are found in parts of the Llanos, particularly in Venezuela.
      • Tourism: The unique ecosystem attracts ecotourists and wildlife enthusiasts.
    5. Cultural Significance:
      • The Llanos are integral to the Llanero culture (the people of the Llanos), known for their traditional music, cowboy lifestyle, and festivals.

    Ecological Importance:

    The Llanos play a crucial role in maintaining the ecological balance of the Orinoco River basin. Seasonal flooding supports the life cycle of many aquatic and terrestrial species, making it a key habitat for wildlife.

    The Llanos are tropical grasslands rich in biodiversity and cultural history, serving as a vital ecological region and a significant economic area for Venezuela and Colombia.

    1. Lion-tailed Macaque: This species is primarily diurnal, meaning it is active during the day and rests at night. They are known for their distinctive mane and tail tuft, and they inhabit the rainforests of the Western Ghats in India.
    2. Malabar Civet: The Malabar Civet is generally nocturnal. It is most active during the night and is rarely seen during the day. It is a critically endangered species native to the Western Ghats and nearby regions.
    3. Sambar Deer: The Sambar Deer is largely nocturnal or crepuscular (active during twilight). It tends to be most active during the early morning and late evening but can also be seen foraging at night.

    Given this information, two of the listed fauna (Malabar Civet and Sambar Deer) are generally nocturnal or most active after sunset. Therefore, the correct answer is: Only two.

    The correct answer is: Honey Bees. Honey bees perform the “waggle dance” to communicate the direction and distance of a food source to other members of their hive. The dance involves a series of movements, including waggling their bodies and making figure-eight patterns, to convey information about the location of nectar, pollen, or water. This sophisticated form of communication is crucial for the foraging efficiency and survival of the colony. Neither butterflies, dragonflies, nor wasps use this method of communication.

    Let’s evaluate the above statements:

    1. Amarkantak Hill:
      • Recognized as a significant natural heritage site.
      • Serves as the junction of the Vindhya and Satpura Ranges.
      • Therefore, statement 1 is INCORRECT.
    2. Biligirirangan Hills:
      • Located in the southeastern region of Karnataka.
      • The Satpura Range, in contrast, begins in eastern Gujarat and extends eastward, bordering Maharashtra and Madhya Pradesh, ultimately reaching Chhattisgarh.
      • Hence, statement 2 is INCORRECT.
    3. Seshachalam Hills:
      • Part of the Eastern Ghats in southern Andhra Pradesh.
      • The Western Ghats, however, span across several states including Kerala, Tamil Nadu, Karnataka, Goa, Maharashtra, and Gujarat.
      • Thus, statement 3 is INCORRECT.

    Therefore, the correct answer is None.
