The correct option is D Abscisic acid
Abscisic acid is a plant hormone. It is widespread in vascular plants. However, in bryophytes, mosses, ferns, algae, it is replaced by lunularic acid. Lunularic acid plays similar role as that of abscisic acid. It acts as growth inhibitor.
Thus, the correct answer is option D.
