B Correct answer
Explanation

Photomorphogenesis is light-dependent development in plants throughout the life cycle, not just at seedling stage. Phytochrome is the key pigment involved (A is true). Red, far-red, and blue light all affect photomorphogenesis (C is true). D correctly defines it. B is FALSE because photomorphogenesis continues throughout plant life - affecting flowering, shade avoidance, circadian rhythms, and other developmental processes in adult plants.
