Answer 2

Option 3 is correct.

Explanation:

• Hyperconjugation is the process by which the alpha hydrogens of the carbanion gets delocalised and thus the charge delocalises, thereby increasing the stability of the species.

• In Hyperconjugation the presence of alpha hydrogens is a must.

• In species 1, we can see there's no alpha hydrogen because of the presence of phenyl group on one side and a tertiary alkyl group on another.

• In species 2,we can see three phenyl groups on the carbanion.

• So no alpha hydrogen is present.

• Alpha hydrogen is present in species 3.

• So Hyperconjugation will occur in species 3 only.
