Question

in an argument, concession refers to...
snacks that you buy at an event.
stating something that is true about the opposing argument.
giving up on the argument.

Explanation:

In academic and rhetorical contexts, a concession in an argument is a rhetorical device where a speaker or writer acknowledges a valid point from the opposing side to build credibility and strengthen their own overall argument. The other options are incorrect: the first is a play on the word "concession" as event snacks, and the third misrepresents concession as abandoning the argument entirely.

Answer:

stating something that is true about the opposing argument.
