(a) Water <Acetic acid <Hydrochloric acid
(b) Water <Hydrochloric acid <Acetic acid
(c) Acetic acid <Water <Hydrochloric acid

Answer: (a)

Acetic acid is an organic acid and ionises only partially in water, hence, it is a weak acid. Water is neutral .
Thus, the order of acidity is
water < acetic acid < hydrochloric acid.
