An aqueous solution of formic acid cannot be fractionated to get anhydrous acid because:

Ait explodes on warming
Bits boiling point is about the same as that of water
Correct Answer
Cit decomposes in aqueous medium
Dit polymerises on warming

Solution

An aqueous solution of formic acid cannot be fractionated to get anhydrous acid because its boiling point is about the same as that of water.
Hence, Option "B" is the correct answer.
