B Correct answer
Explanation

The ideal NPK ratio 4:2:1 is widely recommended for Indian soils because it matches the nutrient requirements of most crops grown in the country's tropical climate. This ratio provides adequate nitrogen for vegetative growth, phosphorus for root development, and potassium for disease resistance and yield.
