The prefix meaning 'cold' is.

• A. Crypto
• B. Cyan(o)
• C. Cryo
• D. Corp

Answer: (C)

Cryo- is the prefix that means cold. It comes from a Greek word for cold and is used in medical terms to describe processes or conditions involving low temperatures, such as cryotherapy (treatment using cold) or cryopreservation (preserving biological material at very low temperatures). That makes it the best fit for the meaning “cold.”

Crypto- means hidden, not cold; cyan(o)- relates to a blue color (as in cyanosis); and corp- or corpus- refers to the body or flesh.
