Considering the elements B, C, N, F, and Si, the correct order of their non-metallic character is: 

(a) B > C > Si > N > F 

(b) Si > C > B > N > F 

(c) F > N > C > B > Si

(d) F > N > C > Si > B

The non-metallic character of elements increases from left to right across a period. Thus, the decreasing order of non-metallic character is F > N > C > B. Again, the non-metallic character of elements decreases down a group. Thus, the decreasing order of non-metallic characters of C and Si are C > Si. However, Si is less non-metallic than B i.e., B > Si. Hence, the correct order of their non-metallic characters is F > N > C > B > Si.
