In summer, the green pigments or the chlorophyll are high, while in fall the chlorophyll lowers because there is less sunlight.

chlorophyll is a green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis. Its molecule contains a magnesium atom held in a porphyrin ring.

Answer:

The correct answer will be options-B and D
