Detailed Solution

Due to the fact that lone pairs of electrons are more localized than bonding electrons and as a result have a higher electron density, they can significantly contribute to the size of a molecule dipole moment.

The determined direction of the electric dipole moment, which shifts from a negative charge to a positive charge, makes it a vector quantity (a quantity with both magnitude and direction).

Because the intermolecular interactions are greater in high-polarity compounds, they often have higher boiling points than low-polarity compounds.

Therefore, it takes more energy for the molecules to separate from these intermolecular interactions. Here, Cl and I have distinct electronegativities, making ICl polar and bromine non-polar.

Hence, option A, B and D are correct.
