Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Benzaldehyde is more reactive than ethanol towards nucleophilic attack.
The overall effect of $- I$ and $+ R$ effect of phenyl group decreases the electron density on the carbon atom of $> C = O$ group in benzaldehydes.
Hence, option $A$ is correct.
