Ah, this is simple.
Well, the wording is important. You can use context clues to guess that this family doesn't want anyone feeling sorry for them, because they'll just feel worse.
You can automatically eliminate B. Nobody would resent them for having a difficult time.
Fidelity means loyal/faithful (along those lines) so that wouldn't fit either
Antipathy is like hatred. Same as resentment really, so you can eliminate this.
Sympathy means feeling sorry (along those lines)
Your answer is sympathy.
~Hope this helps!
