Solution
The correct option is C ABA
- Abscissic acid (ABA) is also called stress hormone. It is the mildly acidic hormone which functions as a general growth inhibitor by counteracting other hormones (Auxins, gibberellins, cytokinins) or reactions mediated by them. It causes stomatal closure, seed dormancy, antagonist (opposite in function) to gibberellins as gibberellins promotes seed germination.
- So, the correct answer is 'ABA'
