Solution

The correct option is D All of the above
Abscisic acid is a plant growth inhibitor that plays an important role in seed development, maturation and induce dormancy in seeds and buds. Seed dormancy is the condition of seeds that are incapable of germinating even when the conditions suitable for seedling growth are supplied. It also promotes senescence, i.e., the process of ageing in plants.
