Assertion : Aldol condensation can be catalysed both by acids and bases. Reason : $\beta$-Hydroxy aldehydes or ketones readily undergo acid catalysed dehydration.
  1. If both assertion and reason are true and reason is the correct explanation of assertion
  2. If both assertion and reason are true but reason is not the correct explanation of assertion
  3. If assertion is true but reason is false
  4. If both assertion and reason are false.

Solution

Both carbanions (formed in presence of base) and enol form (formed in presence of an acid) act as nucleophiles and hence add on the carbonyl group of aldehydes and ketones to give aldols.
