The colour of light LEAST absorbed by chlorophyll (and most reflected by leaves) is:
ARed (around 660 nm strongly absorbed)
BBlue (around 430 nm strongly absorbed)
CViolet (very strongly absorbed)
DGreen (which is why leaves look green)
Answer & Solution
Correct answer: D. Green (which is why leaves look green)
Chlorophyll absorbs RED + BLUE most strongly.
GREEN is reflected/transmitted (why leaves appear green).
Hence green light is the LEAST effective for photosynthesis.
Action spectrum mirrors this.
