The fallacy used when a person is given only two choices to support an argument is called the "Either-or argument" or "False Dilemma." This fallacy occurs when someone presents a situation as if there are only two options or outcomes, ignoring the possibility of other alternatives or nuances that exist in reality.
Here's an example to illustrate this fallacy:
Person A: "Either you support this policy, or you are against progress."
In this case, Person A is using the either-or argument by presenting only two extreme options without acknowledging the possibility of a middle ground or alternative viewpoints.
Therefore, the correct answer to the question is:
D. Either-or argument
