The best summary of the excerpt is B) “Huskies are resourceful and able to take care of themselves during the summer when men do not use them to pull dog sleds.” The text introduces that during the summer huskies are not needed; therefore they are left on their own and they find resources to eat.
Option A is incomplete as it does not mention what huskies do during summer.
Option C only describes animals but do not explain in which context.
Option D is a phrase within the text but does summarize its content.
