Solution

The correct option is C four
An oxygen atom contains six valence electrons. It combines with another oxygen atom to form an oxygen $(O_{2})$ molecule. During this, two electron pairs i.e. four electrons are shared between the two atoms as shown below leaving behind four electron pairs. These four electron pairs do not participate in bonding.
