The correct answer is: From hunting-gathering to settled agriculture.

Explanation:

The Neolithic Revolution marks a significant transformation in human history when societies shifted from a nomadic, hunting-gathering lifestyle to one of settled agriculture and domestication of animals. This transition occurred around 10,000 BCE in different parts of the world.

Key Features of the Neolithic Revolution:

1. Agriculture:
   • Cultivation of crops like wheat, barley, rice, and maize began.
   • It allowed for food surplus, leading to population growth.
2. Domestication of Animals:
   • Animals like sheep, goats, cattle, and pigs were domesticated for food, labor, and other resources.
3. Sedentary Lifestyle:
   • People started living in permanent settlements, giving rise to early villages and communities.
4. Stone Tools:
   • Tools became more specialized, such as sickles and grinding stones for farming activities. However, metal tools came much later.
5. Social Organization:
   • With surplus food, societies began to develop divisions of labor and complex social structures.

Why the Other Options Are Incorrect:

1. From stone tools to metal tools:
   • This transition occurred later, during the Chalcolithic and Bronze Ages.
2. From nomadic life to urbanization:
   • Urbanization happened much later, during the Bronze Age, after the development of cities like those in Mesopotamia and the Indus Valley.
3. From nomadic life to urbanization (duplicate option):
   • Urbanization was not a direct feature of the Neolithic Revolution.

Thus, the Neolithic Revolution is best characterized by the transition from hunting-gathering to settled agriculture.
