Which root denotes the color yellow?

• A. Flav
• B. Cyano
• C. Xantho
• D. Xanth

Answer: (D)

The color yellow is carried by the root xanth-, which comes from the Greek xanthos meaning yellow. This form is the foundation used across medical and scientific terms to denote yellow coloration, appearing in words like xanthoderma (yellow skin), xanthophyll (yellow pigment), and xanthochromia (yellowish color of fluids). Because it’s the primary, base form that signals yellow in a wide range of terms, it’s the best choice to represent the color yellow. The other options reflect related or different color roots (flav- from Latin flavus for yellow, cyano- for blue, xantho- a variant used before vowels), but the standard root signal for yellow is xanth-.
