The correct answer is C. complex.
A complex sentence contains one independent clause and at least one dependent clause. Here, the independent clause is <em>Galileo, the first astronomer to use a telescope, confirmed the theory </em>and the dependent clause is <em>that the earth and planets circle the sun.
</em>A is incorrect because a simple sentence contains only one independent clause; B is incorrect because a compound sentence contains at least two independent clauses; D is incorrect because a compound-complex sentence contains one independent clause and at least two dependent ones.

<span>Boxer - the workhorse. He believes things will get better if he works harder and trusts the pig leadership will help him. He is considered the metaphor for the common people in Russia whom believed the Revolution and overthrow of the Russian monarchy would help them. They are trusting and easily manipulated like Boxer.
Benjamin - the cynical goat. He has seen the cycle of power struggles and knows that nothing will get better with the pigs' leadership. He is never really happy and trusts no animals but Boxer and loves him until Boxer is taken away to his death.
