The electrongativity of the following elements increases in the order :

Options

A.C, N, Si, P
B.N, Si, C, P
C.Si, P, C, N
D.P, Si, N, C

Solution

On moving L → R across a period electronegatively increases, whil on moving down in a group it decreases. In the periodic table relative position of these element is
    
thus correct order is Si < P < C < N
