• C. Chlorophyll
• D. Cytochrome

Answer 1

The correct option is A Phytochrome

Nonphotosynthetic pigments are those pigments which function other that of photosynthesis. They mostly perform functions like growth and development.

• Chlorophyll is the primary green colored pigment which performs the process of photosynthesis (formation of glucose from water, oxygen, and sunlight).
• Xanthophylls and carotenoids are the photosynthetic pigments and functions in the photosystems and cyclic and noncyclic photophosphorylation.
• Cytochromes are the pigments which play, the major roles in photosynthesis and process of electron transport.
• Phytochromes are the hormones or pigments which function according to the movement of light and helps in the growth and development of plants.
