The Pr form of phytochrome absorbs maximally at approximately:

Answer: C) 660 nm. For PHYTOCHROME, remember the key idea and you’ll land on this option; the distractors usually swap cause and effect or confuse similar terms. Avoid: A) 450 nm; B) 550 nm; D) 730 nm. Name the process first, then pick the option that describes it — don’t reverse cause and effect.
