The correct answer is C. The excerpt evades the issue of pay discrimination for women by noting that others are also underpaid.
Explanation:
In a fallacious argument, the speaker tries to support or refute a specific point of view but does not provide real evidence for it even when the argument might sound convincing. Fallacy includes using evasion or changing the topic that is being discussed, this occurs in the argument "Women aren’t the only ones who are underpaid" because the speaker is trying to argue against women being underpaid but instead of providing evidence he/she evades the issue and changes the topic.
