    Answer:. Valence electrons are shared between oxygen atoms.

    B. A double covalent bond is formed.

    Explanation: Oxygen has atomic number 8 and is come under group 6.

    Number of electrons in the outer most shell are known as Valence electrons of that atom. Oxygen has 6 Valence electrons and the valency of oxygen atom is 2. That's mean it can share 2 of its electrons to form a bond.

    So, total valency in O2 molecule is 4. Each of the oxygen molecule share it's 2 electrons and form double covalent bonds.

    By sharing two electrons by each of the oxygen atom it's outermost shell filled and it became stable oxygen molecule (O2).

    O2 has two double covallent bond!

    Thus A and B are correct! The electrons are shared and a double covalent bond is formed!
