Solution

Aldol condensation is a condensation reaction in which an enol or an enolate ion reacts with a carbonyl compound to form a β-hydroxyaldehyde or β-hydroxyketone followed by dehydration to give a conjugate enone, i.e., aldehyde or ketone should have at least one α-hydrogen, which undergoes the reaction with dilute NaOH+β-hydroxy carbonyl compounds gives aldol condensation.

Reagents:

Dilute KOH, NaOH, Na2CO3, CaOH2 or dilute acid.

Hence, the correct answer is option: 'D'.
