The correct answer is option 3: K. V. K Sundaram.
Option 1, Sukumar Sen, was the first Chief Election Commissioner of India, not the second. Option 2, S. P. Sen Verma, and option 4, T. Swaminathan, were not Chief Election Commissioners of India at all. Therefore, the only correct option is option 3. It is important to pay attention to the details and read the question carefully in order to choose the correct answer.
