Answer 1

The correct option is B Borthwick and Hendrick

Borthwick and Hendrick coined phytochrome. Phytochrome is a photoreceptor, a pigment that plants use to detect light. It is sensitive to light in the red and far red region of the visible spectrum. Many flowering plants use it to regulate the time of flowering based on the length of day and night and to set circadian rhythm.
