Correct option is A)

Hint: Given similar molecular mass, the intermolecular force of attraction of functional groups determines their boiling point. The stronger the intermolecular force of attraction, the higher the boiling point.

Explanation:
Step 1: Identify the functional group in each compound:
A)
B)
C)
D)

Step 2: Identify the type of intermolecular force in each compound:
A) H-bonding (Due to presence of electronegative attached to )
B) Dipole-dipole interaction (more dipole moment)
C) London dispersion forces
D)Dipole-dipole interaction (less dipole moment)

Step 3: Arrange them in the order of strength of their intermolecular forces. This will be the same as the order of boiling point.

Since H-Bonding> Dipole-dipole interaction> London dispersion forces, the order of boiling point will be:
