Green, yellow, and indigo wavelengths of light are least absorbed by:

Explanation

Chlorophylls are the primary pigments in plants responsible for photosynthesis. They absorb light most effectively in the blue (around 430 nm) and red (around 680 nm) wavelengths but are less efficient in absorbing green, yellow, and indigo light. This is why chlorophyll-containing tissues, like leaves, appear green to our eyes. On the other hand, carotenes and xanthophylls are types of carotenoids that absorb different spectra of light, complementing chlorophylls by capturing energy that chlorophylls do not absorb efficiently. Carotenoids generally absorb blue light and reflect red, orange, and yellow, contributing to the colours of fruits and flowers, but are not as involved in the primary absorption for photosynthesis compared to chlorophylls.
