B

Green

C

red and green

D

Violet

Text Solution

Verified by Experts

The correct Answer is:
B
Blue and red regions of the light spectrun are most effective in photosynthesis. Blue wavelengths of light carry more energy while red wvelengths have lesser energy. Therefore, the most efficient wavelengths of light effective in phosynthesis are those of red light. Green light is least effective in photosynthesis.
