Which prefix means three?

Explanation:
Numbers in medical terms are shown by prefixes; tri- denotes three. You can see this in words like triceps (three heads), triangle (three angles), and tricuspid valve (three cusps). The other options correspond to two (bi-), four (quad-), and half (hemi-), so they don’t fit the meaning of three.
