The carbonyl carbon is sp2 hybridised and forms three sigma bonds. Thus carbonyl carbon and three atoms attached to it he in the same plane and π-electron cloud is above and below this plane.

Q. Assertion: In formaldehyde all the four atoms lie in one plane.
Reason : Carbonyl carbon forms a $π$ -bond with oxygen by overlapping of $p$ -orbitals.

If assertion is true but reason is false

If both assertion and reason are false

The carbonyl carbon is $s p^{2}$ hybridised and forms three sigma bonds. Thus carbonyl carbon and three atoms attached to it he in the same plane and $π$ -electron cloud is above and below this plane.
