Final answer:
Chlorophyll best absorbs red and blue light, with peaks in the absorption spectrum for chlorophyll a located in the blue and red areas of the spectrum, leading to the reflection of green light and the green color of plants.
Therefore, option B is correct.
Step-by-step explanation:
Chlorophyll Absorption Spectrum
The color of visible light that chlorophyll absorbs the best are red and blue. Chlorophyll a, in particular, is a form of chlorophyll that absorbs violet-blue and red light but reflects green light, giving plants their characteristic green appearance. This reflection occurs because chlorophyll a does not absorb green wavelengths effectively. In an absorption spectrum, chlorophyll a shows peaks in the blue (around 430-470 nm) and red (around 640-680 nm) regions. Photosynthesis is optimized when plants are exposed to wavelengths of light that chlorophylls can absorb well, which include these portions of the spectrum.
