Which prefix means before?

Explanation:
Prefixes modify the meaning of a root to show timing or condition. The one that means before is pre-, as in predict, preview, preoperative. It signals something happening earlier or in advance. The other options point to different ideas: post- means after; dys- indicates difficulty or abnormality; tachy- means fast. So pre- is the correct choice because it directly conveys the sense of before.
