The correct answer is (b) G.V. Mavlankar.
G.V. Mavlankar was the first Speaker of the Lok Sabha, the lower house of the Parliament of India. He was elected Speaker on 15 August 1950, the day India became a republic. He was a member of the Indian National Congress and served as Speaker until his death in 1956.
In 1953, a motion of no confidence was moved against Mavlankar by the Communist Party of India. The motion was defeated, but it was the first time that a motion of no confidence had been moved against the Speaker of the Lok Sabha.
B.R. Jhakhad was the Speaker of the Lok Sabha from 1977 to 1979. Hukum Singh was the Speaker of the Lok Sabha from 1980 to 1984. K.S. Hegde was the Speaker of the Lok Sabha from 1985 to 1989.
B.R. Jhakhad was a member of the Janata Party. Hukum Singh was a member of the Bharatiya Janata Party. K.S. Hegde was a member of the Janata Dal.
None of these three Speakers were moved a motion of no confidence.
