Which nutrients are primarily responsible for soil fertility issues in Pakistan, considering that deficiencies of nitrogen (N), phosphorus (P), and zinc (Zn) are widespread, while potassium (K), iron (Fe), and boron (B) deficiencies occur in certain crops or soils, and sulfur (S), copper (Cu), and manganese (Mn) deficiencies are minimal? Additionally, some micronutrients like molybdenum (Mo) may also be deficient.

Explanation

Soil fertility challenges in Pakistan mainly involve deficiencies in nitrogen (N), phosphorus (P), and potassium (K). Although calcium (Ca), magnesium (Mg), and sulfur (S) may also be deficient in some cases, the primary concern is with N, P, and K. Therefore, the correct answer includes both nutrient groups, making option C the most accurate.
