Question

Then A is:

Answer 1

Answer: (B)

Answer 2

'C' must be an isocyanide, which is derived from a primary amine through the Carbylamine reaction $(CHCl_3+KOH)$. Additionally, the primary amine must be produced through the reduction of a nitro hydrocarbon. Therefore, 'A' is nitrobenzene.

So, the correct option is (B).
