• A. Leuko
• B. Hem
• C. Gyne
• D. Irid

Answer: (A)

The idea here is recognizing prefixes that denote color in medical terms. Leuko- means white, from the Greek leukos, and it’s used in terms like leukocyte (white blood cell) or leukoderma (loss of pigment giving a white appearance). That makes it the best fit for the clue “White.” The other roots point to something other than color: Hem- or hemo- means blood, gyne- relates to women, and irid- refers to the iris of the eye (or, from the same root, colors like rainbow in other uses). So they don’t convey the meaning of white.
