Question

Which ones are primarily absorbed by carotenoids?

• A. Blue and green
• B. Green and red
• C. Red and violet
• D. Violet and blue

Answer 1

The correct option is A Blue and green

Carotenes are unsaturated hydrocarbons with a general formula of C${}_4$${}_0$H${}_5$${}_6$. They absorb blue and green lights and appear yellow and red in colour. The most common carotene is $\beta$ - carotene which is converted to Vitamin A by animals and human beings.

Hence, the correct answer is 'Blue and green'.
