PHYTOCHROME+PYQS

Phytochrome apoprotein alone cannot absorb light because:

B fits best: It lacks chromophore. Keep the PHYTOCHROME basics straight and It lacks chromophore stands out as the precise answer. Avoid: A) It lacks PAS domain; C) It is monomeric; D) It is unstable. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.
