Answer:
Buck learns quickly because his teachers are strict and unforgiving
Explanation:
According to the excerpt from The Call of the Wild by Jack London, Buck was intentionally placed between Dave and Solleks because he was a keen learner who obeyed instructions. 
His instructors Dave and Francois were ready to nip him when he strayed so because of this, he kept in line and kept Dave and Solleks in line too
Buck's behavior supports the theme that "one must lead with a firm hand" because his teachers never fail to nip him if the need arises.

An independent clause is a clause or a part of a sentence that can also be another sentence on its own. It has its own subject and predicate.
Of all the sentences given, letter B has an independent clause. Why is that?
In letter B, the sentence "Alan wants to visit his friends before he returns to college." can be broken down into two sentences.
1. Alan wants to visit his friends.
2. He returns to college.
In this case, we have 2 independent clause in one sentence which is why letter B is the answer.
