Solution

The correct option is D acetone
Acetylene reacts with Hg+2/H2SO4 to form acetaldehyde (B).
Then acetaldehyde reacts with CH3MgX/H2O to form 2-propanol (C), which undergoes oxidation to form acetone (D).

CHCHHg+2/H2SO4−−−−−−−CH3CHOCH3MgX−−−−−CH3CH(OH)CH3(O)CH3COCH3

So final product D is Acetone.
