Solution

The correct option is A Si, P, C, N
On moving along a period from left to right in a periodic table, electronegativity increases ( due to the decrease in size). While moving downward in a group, electronegativity decreases.

Thus, the correct order of electronegativity is: $S i < P < C < N$ .

Hence, option A is correct.
