Answer -  (c) F > N > C > B > Si

Because non-metallic character of an elements increases from left to right across the period. And here given position of elements:

Boron (B)  -  2^{nd} period and 13^{th} group.

Carbon (C)  -  2^{nd} period and 14^{th} group.

Nitrogen (N)  -  2^{nd} period and 15^{th} group.

Fluorine (F)  -  2^{nd} period and 17^{th} group.

And the Silicon (Si) is present in the 3^{rd} period and  14^{th} group.

Hence the correct order of non-metallic character is as follows:

F > N > C > B > Si
