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 becuase the -I and +R effect C6H5 group decreases the electron density on carbonyl carbon and makes it +vely charged and fecilitate the nucleophile attack . So Both Assertion and Reason are correct and Reason is the correct explanation for Assertion Hence option A is correct.
