(a) NCl5
Explanation:
From the given list of compounds, NCl5 does not exist. NCl5 does not exist because nitrogen atom does not have d-orbitals to accommodate electrons from chlorine atoms, and nitrogen can't accommodate more than 8 electrons in its valence shell. So its covalency exists only up to four.
Option A is the answer.
