Solution

The correct option is C Violet and blue
Chlorophyll and carotenoid are the important pigments of the photosynthetic plants. These pigments can absorb light in the range of 700nm to 400 nm. Carotenoid pigment is present in thylakoid and absorbs light violet and blue and reflects longer wavelength i.e., yellow, red and orange light.
