Correct answer: (b) III, I, IV, II
Explanation
- A
I, II, III, IV
I, II, III, IV puts Ashok Mehta and Singhvi before Balwant Rai Mehta, which reverses the 1950s starting point of the Panchayati Raj committee series. This option is not the key.
- B
III, I, IV, II
III, I, IV, II is the official chronological order: B.R. (Balwant Rai) Mehta Committee, Ashok Mehta Committee, G.K.V. Rao Committee, then L.M. Singhvi Committee. Balwant Rai Mehta reported in 1957 and recommended the three-tier system. Ashok Mehta followed in 1977–78. G.K.V. Rao reported in 1985 and Singhvi in 1986. That sequence is (b).
- C
II, I, III, IV
II, I, III, IV starts with Singhvi, the latest of the four. This option is therefore wrong.
- D
III, II, IV, I
III, II, IV, I places Singhvi before Ashok Mehta and Rao, which is not the historical order. This option is not the key.
Summary. Official key is (b) III, I, IV, II. The committee chain begins with Balwant Rai Mehta in 1957, then Ashok Mehta after the Emergency, then G.K.V. Rao, then L.M. Singhvi on the eve of the 73rd Amendment debates. The paper’s “B.R. Mehta” is that 1957 committee. Only (b) is correct.
