Which prefix means "backwards"?

• A. Before, for, an account of
• B. One
• C. Backwards
• D. False

Answer: (C)

Prefixes modify the root to show direction or relation. When a prefix means backward, we commonly think of retro-, which signals looking back in time or behind in position. In many medical terms this sense is clear: retrospect, retrograde, retroactive—all convey backward direction. Among the options, the one that directly conveys that meaning is the word that literally means backwards. That is why it fits best for a prefix question asking for backwards. The other choices point to different concepts—before (a sense of earlier time), one (a unit), or false (negation or deception)—and do not express backward direction. Understanding that backward meaning is captured by the concept of something happening retroactively or in reverse helps you see why the chosen option is the correct fit.
