Which salt formulation enables IBA to be dissolved in water? (RJ AARO Horticulture 2022)

✅Explanation:
IBA (Indole-3-butyric acid) is a plant hormone that promotes root growth. In its pure form, IBA is not readily soluble in water. However, when formulated as a potassium salt (K-IBA), it becomes water-soluble, making it easier to use in horticulture and agriculture.
