Which one of the following did NOT serve as Vice President before assuming the Office of the President of India?

1. A

   Dr. Shankar Dayal Sharma

   Option (a) claims Dr. Shankar Dayal Sharma served as Vice President before becoming President. He indeed served as the ninth Vice President of India from 1987 to 1992 before assuming the presidency in 1992, making this option incorrect for the negative stem.

2. B

   Neelam Sanjiva Reddy

   Option (b) claims Neelam Sanjiva Reddy did not serve as Vice President before becoming President. He served directly as the Speaker of the Lok Sabha and Union Minister before winning the presidential election in 1977 without holding the vice-presidential office, making this the correct answer.

3. C

   Dr. Zakir Hussain

   Option (c) claims Dr. Zakir Hussain served as Vice President prior to his presidency. He served as the second Vice President of India from 1962 to 1967 before being elected as the President of India in 1967, which renders this option incorrect.

4. D

   R. Venkatraman

   Option (d) claims R. Venkatraman served as Vice President before his presidency. He held the office of the eighth Vice President of India from 1984 to 1987 before stepping up to become the President in 1987, thus making this option incorrect.

Summary. Official key is (b) Neelam Sanjiva Reddy did not serve as Vice President before assuming the Office of the President of India. Dr. Zakir Hussain, R. Venkatraman, and Dr. Shankar Dayal Sharma all held the office of Vice President before ascending to the highest office of the nation. Neelam Sanjiva Reddy went straight from active parliamentary politics and the Lok Sabha speakership to the presidency in 1977. Aspirants often confuse the career paths of various Indian presidents due to overlapping timelines. Careful chronological revision of constitutional officeholders is essential to avoid such negative framing traps.
