JEE Advanced Chemistry question

HClO4, HNO3 and HCl are all very strong acids in aqueous solution. In glacial acetic acid medium, their acid strength is such that

(A)HClO4 > HNO3 > HClCorrect
(B)HNO3 > HClO4 > HCl
(C)HCl > HClO4 > HNO3
(D)HCl > HClO4 ~ HNO3

Answer: (A)

Solution

Water is such a strong base relative to these three acids that it "levels" them all to the same apparent strength (all simply ionise completely, appearing equally strong). Glacial acetic acid, however, is a much weaker base and
