C Correct answer
Explanation

A molecule of oxygen contains two oxygen atoms joined by a double covalent bond.Thus, the two atoms of oxygen share two electrons each and do not require any more electrons because they have already attained stable octet configurations. If an atom of oxygen having six electrons comes closer to the oxygen molecule, the new atom may share a lone pair of electrons from either of these two oxygen atoms, which donates to the third oxygen atom without sharing any of the electrons of the third oxygen atom. As a result, a coordinate bond is formed between one of the oxygen atoms of the oxygen molecule, and the third atom of oxygen.
