Solution

The correct options are
A alkanes
B alcohols
D esters
Carboxylic acids have high boiling points because of extensive association of their molecules via intermolecular hydrogen bonding. Even in vapour phase the hydrogen bonds remain intact and most of the carboxylic acids exist as dimers in vapour phase or in aprotic solvents.
