Solution

The correct option is B
The addition reaction of enol or enolate to the carbonyl function of aldehyhde or ketone is known as aldol addition. The $β -$ hydroxyaldehyde or $β -$ hydroxyketone so obtained undergo dehydration in second step to produce a conjugated enone. The first part of reaction is an addition reaction and the second part is an elimination reaction.

The most characteristic reaction of aldehyde and ketones is nucleophilic addition to carbon oxygen double bond. Aldehyde and ketones are easily susceptible to nucleophilic addition because of structural features. The trigonal planar arrangement of groups around the carbonyl carbon atom means that the carbonyl carbon atom is relatively open to attack from above and below the plane of carbonyl group. The partial positive charge on the carbonyl atom means that it is especially susceptible to attack by a nucleophile
