Which prefix corresponds to the meaning 'Lump, clot'?

Explanation:
Thromb- denotes a clot or lump. It comes from Greek thrombós, meaning clot. In medical terms you’ll see it in thrombosis (the formation of a clot inside a blood vessel) and thrombus (the clot itself). That fits the meaning “Lump, clot.” The other prefixes don’t relate to clots: phob- means fear, phot- relates to light, and rachi- refers to the spine. So thromb- is the correct fit because it specifically ties to clot-related concepts.
