Answer:
Buck is willing to compromise morality for survival
Excerpt (you forgot to include it in your question):
To remedy this, [Buck] ate as fast as they; and, so greatly did hunger compel him, he was not above taking what did not belong to him. He watched and learned. When he saw Pike, one of the new dogs, a clever malingerer and thief, slyly steal a slice of bacon when Perrault's back was turned, he duplicated the performance the following day, getting away with the whole chunk. A great uproar was raised, but he was unsuspected; while Dub, an awkward blunderer who was always getting caught, was punished for Buck's misdeed.
What do you need help on?
The subordinate clause in this sentence is "<span>as do some species of fish, amphibians, mammals, turtles, lizards, snakes, and crocodiles."
A subordinate clause is one which is dependent and cannot exist on its own - it has to be located within a larger, independent sentence to make sense. A is incorrect because that is the independent clause, B is incorrect because that is not the complete subordinate clause, and C is incorrect because there is no verb so it cannot be a clause but rather a phrase.
