N

Explanation:

Considering Ground state Electronic configuration
C=1s^2 2s^2 2p_x^1 2p_y^1 2p_z^0->C=1s22s22p1x2p1y2p0z 2unpaired electron
N=1s^2 2s^2 2p_x^1 2p_y^1 2p_z^1->N=1s22s22p1x2p1y2p1z 3unpaired electron
O=1s^2 2s^2 2p_x^2 2p_y^1 2p_z^1->O=1s22s22p2x2p1y2p1z2unpaired electron
F=1s^2 2s^2 2p_x^2 2p_y^2 2p_z^1->F=1s22s22p2x2p2y2p1z1unpaired electron
