Answer:
The claim is the starting point of an argument. (B)
Explanation:
There are four parts in an argument – claim, counterclaim, reason and evidence. A claim is a way by which you state the main point of the argument. Claims are not opinions. They tell what you think is true about a certain topic based on your knowledge and research. For example, you want your father to get you a new laptop so you need a claim to explain why you need to discard the old one.
