Solution:

Compounds with $CH _{3}- \overset{\underset{||}{O}}{C} -$ or $CH _{3}- CH ( OH )$-group gives haloform reaction but this reaction is given only by aldehydes, ketones and alcohols, so acetic acid does not give haloform reaction. However acetic acid has three $\alpha- H$, therefore, statement I is true but statement II is false.
