Answer
Please see the work below.
Work Step by Step
We know that the bonding about the carbon atom is trigonal planar geometry with the carbon atom having $sp^2$ hybrid orbitals. The carbon oxygen double bond is a $\sigma $ bond that is formed by the overlap of $sp^2$ orbital on carbon with 2p orbital on oxygen and a $\pi$ bond by the overlap of an unhybridized $2p$ orbital.
