Using the codes given below, identify the Vice-President/s of India's Constituent Assembly:
a. B.N. Rau
b. H.C. Mookerjee
c. V.T. Krishnamachari
d. G.V. Mavalankar

Question

Accepted Answer

Option 4 is the correct answer because it identifies H.C. Mookerjee and V.T. Krishnamachari as the Vice-Presidents of India's Constituent Assembly. Here is a detailed explanation supporting this choice:

1. **H.C. Mookerjee**: He was indeed one of the Vice-Presidents of the Constituent Assembly. H.C. Mookerjee played a significant role in the proceedings of the Assembly and was known for his contributions to the debates and discussions that shaped the Indian Constitution.

2. **V.T. Krishnamachari**: He also served as a Vice-President of the Constituent Assembly. His involvement in the Assembly was crucial, and he was recognized for his administrative skills and leadership during the drafting process.

Now, let's examine why the other options are incorrect:

- **Option 1 (b and d)**: While H.C. Mookerjee (b) was a Vice-President, G.V. Mavalankar (d) was not. G.V. Mavalankar was the first Speaker of the Lok Sabha, not a Vice-President of the Constituent Assembly.

- **Option 2 (a and c)**: B.N. Rau (a) was the Constitutional Advisor to the Constituent Assembly, not a Vice-President. V.T. Krishnamachari (c) was a Vice-President, but pairing him with B.N. Rau makes this option incorrect.

- **Option 3 (only b)**: While H.C. Mookerjee (b) was indeed a Vice-President, this option fails to include V.T. Krishnamachari (c), who was also a Vice-President, making this option incomplete.

In conclusion, Option 4 correctly identifies both H.C. Mookerjee and V.T. Krishnamachari as the Vice-Presidents of India's Constituent Assembly, which is why it is the correct answer.
