Solution

The correct option is B Abscisic acid
ABA is a growth inhibitor which retards or suppresses growth and metabolism. It induces bud dormancy in a number of plants. In perennial plants, ABA causes the active axillary buds to become dormant. ABA maintains dormancy in many seeds. It accelerated senescence in leaves.
