Answer:
The correct answer is: A) refuting a counterclaim.
Step-by-step explanation:
Argumentative essays are written to present a thesis on a point of view of a particular subject, with the support of evidence to justify the taken position. In order to make the argumentative essay more successful, the writer has to prevent possible counterclaims by anticipating opposing points and refuting them. The part of the essay in which the author does this is the "refuting a counterclaim" one.
