Solution

The correct option is C Assertion is correct but Reason is incorrect.
Haloform test identifies the presence of a $C H_{3} C O$ group in aldehydes and ketones.

$C H_{3} C O R + 3 I_{2} + 4 O H^{-} \to C H I_{3} + R C O O^{-} + 3 I^{-} + 3 H_{2} O$

Acetic acid does not undergo haloform reaction because in presence of $O H^{-}$ ions it acts as an acid and does not forms $C H X_{3}$ haloform. Therefore assertion is correct.

Acetic acid has three $α$ hydrogens, thus the reason is incorrect.
