Question

Accepted Answer

N, P, K. The question explicitly states that deficiencies of K are common (in specific contexts) and lists N, P, Zn as major. Option A (N, P, K) aligns best with the 'common nutrient deficiencies' mentioned in standard agronomy texts for Pakistan, whereas Ca and Mg are not typically listed as primary deficiency problems alongside NPK in this context.
