Engineers' Day is celebrated in India on 15 September every year to mark the birth anniversary of

  1. A.Homi Jehangir Bhabha
  2. B.Sir M. Visvesvaraya
  3. C.Vikram Sarabhai
  4. D.A. P. J. Abdul Kalam

Correct answer

B. Sir M. Visvesvaraya

Explanation

The correct answer is B, Sir M. Visvesvaraya. Mokshagundam Visvesvaraya was born on 15 September 1861, served as the Diwan of Mysore, and built the Krishnarajasagara dam and the system of automatic sluice gates that made his name. He was awarded the Bharat Ratna in 1955, and Engineers' Day honours him.

Option A, Homi Jehangir Bhabha, was the architect of India's atomic energy programme and is remembered as a physicist rather than an engineer. Option C, Vikram Sarabhai, founded India's space programme, and Indian space landmarks are tied to him instead. Option D, A. P. J. Abdul Kalam, was an aerospace scientist and the eleventh President of India; his birthday, 15 October, is observed as World Students' Day. A candidate who notices the day names the engineer, not the scientist, gets this right at once.
