What is the best way to describe a counter-claim? an opposing viewpoint

a restated viewpoint

another view of the argument

an unrealistic way to look at an argument

A restated Viewpoint

Explanation:

A counter-claim exists to state the limitation of the original claim, it does not describe an unrealistic viewpoint (at least not always), It can be described as an opposing viewpoint, but a counter claim does not come up with a random reason as to why the viewpoint is incorrect, a counter claim takes the original claim (viewpoint) and describes what is wrong with it. It can also be considered another view of an argument, but having a counterclaim does not create another party or group, but rather (as I said) takes what was originally said, and shows what is wrong with it.

Therefore, the best answer (out of the options listed) is B - A restated view point.
