ANitrogen, phosphorus, potassium and calcium
BNitrogen, phosphorus, potassium and molybdenum
CIron, manganese, boron and copper elements
DIron, magnesium, sulfur and zinc elements
Answer & Solution
Correct answer: A. Nitrogen, phosphorus, potassium and calcium
1. The macronutrients are carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium and sulfur.
2. Nitrogen, phosphorus, potassium and calcium all appear on that list.
3. Molybdenum, iron, manganese, boron, copper and zinc are trace elements and belong to the micronutrients.
4. So any group containing one of those trace elements cannot be a pure macronutrient list.
