Given data: To find whether assertion or reason or both are right or wrong and find their relation 

Formula / Concept used: Hydrogen bonding       

Detailed solution:

In contrast to the comparable alcohol, carboxylic acids have higher boiling temperatures due to their capacity for intermolecular hydrogen bonding

Because the O-H bond in COOH is more highly polarized due to the presence of an electron-withdrawing carboxy group in the adjacent position compared to the O-H bonds of alcohols, the hydrogen bonds created by carboxylic acids are stronger than those in alcohols

Because of this, lower members of carboxylic acids have boiling temperatures that are greater than those of alcohol with comparable molecular weights

Both are right, reason is not correct explanation of assertion

Hence, the correct option is B.
