  1. A2 onlyCorrect
  2. B1 and 3
  3. C2 and 3
  4. DNone

Explanation

The correct option is A because only the second statement contains accurate information, while the others are incorrect. Statement 1 is incorrect because the Sensex is based on 30 of the largest and most actively traded stocks on the Bombay Stock Exchange, not 50. The index that tracks 50 stocks is the Nifty 50, which belongs to the National Stock Exchange. Statement 2 is correct because the Sensex is calculated using a free float market capitalization methodology. In this system, each component stock is assigned a weightage proportional to its market value available for public trading. Statement 3 is incorrect because the Amsterdam Stock Exchange, established in 1602 by the Dutch East India Company, is considered the oldest stock exchange in the world. The New York Stock Exchange was founded much later in 1792.
