Correct option is C
Gibberellin stimulates the synthesis of hydrolytic enzymes like α-amylase in the aleurone layer of cereal grains.
These enzymes break down starch into sugars, which are then used by the embryo during germination.
Auxin (A): Promotes cell elongation and root formation.
Ethylene (B): Involved in fruit ripening and stress responses.
ABA – Abscisic Acid (D): It inhibits seed germination and promotes seed dormancy, acting antagonistically to gibberellin.
