The capital markets typically include financial markets where long-term debt (bonds) or equity-backed securities (stocks) are bought and sold. Let’s analyze the given options:

1. Government Bond Market: This is part of the capital market as it deals with long-term securities (bonds).
2. Call Money Market: This is part of the money market, not the capital market, as it deals with very short-term funds (usually overnight loans).
3. Treasury Bill Markets: Treasury bills are short-term debt instruments, which are part of the money market, not the capital market.
4. Stock Market: This is part of the capital market as it involves trading equity-backed securities.

Therefore, only two of the above markets, the Government Bond Market and the Stock Market, are included in capital markets. The correct answer is Only two.
