Though express a contrast with what is said in the second part of the sentence, i.e. aristocratic heritage. Thus, the best fits are "impecunious" and "insolvent".

Answer A and F

Explanation

This sentence trickily hinges on the idiom though they now may be, which indicates that whatever comes after the comma is opposite in meaning to the blank.

You learn next that that family seems to act as if they are still aristocrats. The implication is that they are then not aristocrats, or at least don’t have the same wealth that aristocrats are known to have. You’re thus looking for a word that means “poor” or “impoverished.”

Impecunious, which comes from pecunia, Latin word for “money,” and insolvent, which means “unable to pay debts,” are best.

Hence options impecunious, insolvent are correct!
