Text Solution

Verified by Experts

The correct Answer is:
B

Cathoxylic acids are the strongest acids on account of elect-tron withdrawing effect of the carbonyl group while alco-hols are weaker acids than water on account of the electron releasing effect of the alkyl groyp. However, all alcohols are much stronger acids than terminal alkynes.
