I'd appreciate it if you help me with this question, thank you! I'll also be giving brainliest to the best answer. Claim in an argument is most closely defined as:

An opinion about a topic
A firm stance on an issue
An answer to a pressing question
The evidence an author presents

a firm stance on an issue

Explanation:

The claim is what the author or writer is going to talk about in the written work

A firm stance on an issue.

Explanation: This is the most logical choice because in an argument, you cannot be emotional or have opinions on aything really. So your CLAIM has to be firm and reliable. A claim in an argument is usually the issue or main idea that you want to defend. This is why the answer is that one! Hope it helps :)
