Solution

The correct option is D
not conduct electricity

Explanation for Correct Option (D)
Compound X consists of molecules, so it is a covalent compounds and doesn't have any charged ions to conduct electricity.
So in liquid state, X will not conduct electricity due to absence of free ions.
Hence, the correct answer is (D).
