Text Solution

Verified by Experts
The correct answer is:
C

• ABA induces seed dormancy and inhibits germination.

• Gibberellins break seed dormancy and promote germination by inducing the synthesis of amylase, which hydrolyzes stored starch.

While they are involved in other processes, their most classic antagonistic relationship is in regulating seed dormancy and germination, where they act in opposite manners.
