• D. Chlorophyll $b$

Answer 1

The correct option is A Phytochrome

Phytochrome is a plant pigment that is involved in the initiation and regulation of photoperiodism and photomorphogenesis. Phytochromes absorb red and far-red light and signals for a photomorphogenetic response.

Thus, the correct answer is 'Phytochrome'.
