Answer:
B. opponents
Step-by-step explanation:
When you present a counterclaim, you explain what your opponents believe. A counterclaim is a point or argument raised in opposition to or to refute another argument, and it presents an alternative viewpoint to the main argument. In this case, the counterclaim is being used to refute the original argument presented by the opponent. By presenting the counterclaim, the speaker is acknowledging the opposing viewpoint and presenting evidence to show why their argument is stronger.
