During seed germination, its stored food is mobilised by:

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.
