In which of the following, all the three are macronutrients

Options

A. Iron, copper, molybdenum
B. Molybdenum, magnesium, manganese
C. Nitrogen, nickel, phosphorus
D. Boron, zinc, manganese

Answer

To determine which of the following options contains all three macronutrients, we need to first identify what macronutrients are and then analyze the options provided.

### Step-by-Step Solution:

1. **Understand Macronutrients**: Macronutrients are essential nutrients that plants require in larger quantities for their growth and development. The primary macronutrients include Nitrogen (N), Phosphorus (P), and Potassium (K). Other macronutrients include Calcium (Ca), Magnesium (Mg), and Sulfur (S).

2. **Identify the Options**: The question implies that there are multiple options to choose from. We need to look at each option to see if they contain only macronutrients.

3. **Analyze Each Option**:
- **Option A**: If this option contains Iron (Fe), Copper (Cu), and Molybdenum (Mo), these are all micronutrients, so this option is incorrect.
- **Option B**: If this option contains Nitrogen (N), Nickel (Ni), and Phosphorus (P), here Nitrogen and Phosphorus are macronutrients, but Nickel is a micronutrient, so this option is also incorrect.
- **Option C**: If this option contains Boron (B), Zinc (Zn), and Manganese (Mn), all of these are micronutrients, making this option incorrect.
- **Option D**: If this option contains Nitrogen (N), Phosphorus (P), and Potassium (K), all three are macronutrients, making this option correct.

4. **Conclusion**: After analyzing the options, we find that the only option that contains all three macronutrients is the one that includes Nitrogen, Phosphorus, and Potassium.

### Final Answer:
The correct option is the one that contains Nitrogen (N), Phosphorus (P), and Potassium (K), as all three are macronutrients.
