The correct statement is D. A small anion is likely to undergo a large degree of polarization.

Here's why:

Polarization refers to the distortion of the electron cloud of an anion by a cation. The degree of polarization depends on both the cation and the anion.

A cation with a high charge and small radius (high charge density) can polarize an anion more effectively. This is because the cation's positive charge can pull the anion's electron cloud towards itself more strongly.

On the other hand, an anion with a small size (and thus high electron density) is more polarizable. This is because its electrons are closer to the cation and thus more strongly attracted to it.

Therefore, statement D is correct because a small anion, with its high electron density, is likely to undergo a large degree of polarization when near a cation.
