At 25°C, nitrogen exists as N2 and phosphorous exists as P4 because
(A) N2 has valence electrons only in bonding and nonbonding orbitals, while P has valence electrons in both bonding and antibonding orbitals
(B) higher electronegativity of N favours formation of multiple bonds
(C) ** size of P does not favour multiple bonds
(D) P has preference to adapt structures with small bond angles
