Question

• A. Green
• B. Yellow
• C. Violet-blue
• D. Orange-red

Answer 1

Answer: (C)

Violet-blue

Chlorophyll and carotenoids are the major pigments in plants, while there are dozens of carotenoids, there are only five important chlorophylls, a, b, c, d, and bacteriochlorophyll. Chlorophyll a absorbs light in the blue-violet region and reflects green colour.

So, the correct answer is option C.
