Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
The reactivity of a compound towards nucleophillic addition reaction depends on the +ve charge on the cation more the positive it shows more tendency towards nucleophilic substitution reaction.

Due to resonance effect in benzaldehyde, the electron density on carbon increases which decreases the nucleophilicity. So benaldehyde is less reactive in comparison to ethanol towards nucleophilic attack.

All the carbon atoms of benzaldehyde are $s p^{2}$ hybridised. (All the carbon atoms are with double bonds)

So Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.

Hence option B is correct.
