The correct answer is option 3, R. Venkatraman.

Option 1, S. Radhakrishnan is not the author of the book "My Presidential Years". He was the second President of India, serving from 1962 to 1967, but he did not write this book.

Option 2, V.V. Giri is also not the author of the book. He was the fourth President of India, but he did not write "My Presidential Years".

Option 4, K.R. Narayanan, was the tenth President of India, serving from 1997 to 2002. He is not the author of the book mentioned.

Therefore, the correct answer is option 3, R. Venkatraman. He served as the eighth President of India, from 1987 to 1992, and "My Presidential Years" is a book written by him that provides insights into his time as President.
