Solution

The correct option is A CO
A dative bond is a type of bond where only one atom shares the electrons of another atom without affecting it.
In the case of CO Carbon and oxygen together have a total of 10 electrons in the valence shell. Since four of the shared electrons come from the oxygen atom and only two from carbon, one bonding orbital is occupied by two electrons from oxygen, is forming a dative or dipolar bond. So the correct option is A
