Solution
The correct option is B Ethylene
Ethylene is considered as a plant growth promoter as well as a plant growth inhibitor. It promotes abscission of leaves, senescence in plants. It also promotes cell division and growth in plants.
Auxin is a plant growth promoter. It prevents abscission in plants. It promotes growth of root and shoot apex called apical dominance.
Abscisic acid is a plant growth inhibitor. It promotes abscission of leaves, and senescence but it inhibits cell division and growth in plants.
Cytokinin is a plant growth promoter that helps in rapid cell division but prevents senescence.
