Explanation:

The allusion to "Dr. Jekyll and Mr. Hyde" refers to a person with two distinct personalities: one kind (like Dr. Jekyll) and one monstrous/cruel (like Mr. Hyde). The option "kind then cruel" matches this duality, as Jekyll is kind and Hyde is cruel. "Reserved but cold" doesn't capture the dual - personality shift, and "impolite and selfish" only describes the negative side without the positive - to - negative shift.

Answer:

kind then cruel
