Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Cyclohexanone semicarbazone is the kinetically controlled product. Hence, it is formed first.
Semicarbazone of benzaldehyde is thermodynamically controlled product. It is formed later on.
Thus, both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
