Answer: Option B) Vernalization
Abiotic stressors such as temperature extremes or lack of water trigger ABA synthesis, which aids in preventing water loss from the plant.
Explanation:
Either during temperature extremes like very low temperatures or drought conditions, the production of absiccisic acid (ABA), a plant hormone is elevated.
This is due to the need for regulate water levels, and stomatal closure to reduce water loss for plant survival.
Thus, ABA synthesis is the answer
