In option 1, Statement 1 lacks accuracy because Bethune School, the first women`s school in India, was established by John Elliot Drinkwater Bethune, not Ishwar Chandra Vidyasagar.

In option 2, Statement 1 is wrong as we just discussed, but Statement 2 is correct. Bankim Chandra Chattopadhyay was the first graduate of the University of Calcutta.

Option 3 comprises Statements 2 and 3. While Statement 2 is correct, Statement 3 is not. The campaign to abolish Sati was led by Raja Ram Mohan Roy, not Keshav Chandra Sen. The Bengal Sati Regulation was passed by Lord William Bentinck, the then Governor-General of India based on Raja Ram Mohan Roy`s efforts.

In option 4, all the statements are considered correct, but as we have gone through each statement individually, we know that Statements 1 and 3 are incorrect.

Therefore, the correct answer is option 2 which implies only the second statement is correct, i.e., Bankim Chandra Chattopadhyay was the first graduate of the Calcutta University.
