Solution

The correct option is B Intermolecular dipole-dipole attraction
The boiling point generally depends on intermolecular force of attraction. Stronger the force of attraction, higher is the boiling point.
Boiling points of aldehydes and ketones depend on intermolecular dipole-dipole attraction due to the presence of a stronger C=O bond. Hence, the correct answer is option (b).
