Onions prefer slightly acidic to neutral soil (pH 5.5-6.8) for optimal nutrient availability and healthy growth.
📌Other Options Explanations:
-(a) 4.8-5.5: Too acidic, hindering nutrient uptake.
-(c) 6.8-7.5: Slightly alkaline, reducing essential nutrient availability.
-(d) 7.5-8.3: Too alkaline, causing nutrient deficiencies and affecting bulb development.
