Answer 2

Answer:

An aldol condensation is a reaction in which an enol or an enolate ion reacts with a carbonyl compound to form a β-hydroxyaldehyde or β-hydroxyketone (an aldol reaction), followed by dehydration to give a conjugated enone

Carbonyl compounds that contain β-hydrogen can undergo Aldol condensation in the presence of dilute base as:

Therefore only option A will undergo Aldol condensation as others donot have any β-hydrogen.

A is correct
