Anti- as a prefix means which of the following?

• A. For
• B. With
• C. Within
• D. Against each other

Answer: (D)

Anti- signals opposition or being against something. When you see this prefix, think of actions or states aimed at countering, resisting, or opposing something else. In animal interactions, it can describe antagonistic or competitive relations—things that are “against” another, which is captured by the idea of two or more entities opposing each other. The other options describe directions or positions (for, with, within) and do not convey opposition. So the best fit is the idea of being against each other.
