The bonds present in carbonmonoxide molecule are

Bond present in carbon monoxide are Dative.

Dative Bond is a type of alternate covalent bond that is formed by sharing of electron pair from single atom. Both shared electrons are donated by the same atom.

In Carbon monoxide, two bonds are formed by sharing of two electrons from each carbon and oxygen. The third bond is formed by the electron pair donated by oxygen atom.

so, carbon monoxide has a dative bond.

Hence, the correct option is option (C) Dative.
