Which of the followings are macronutrients?

Options

A. Carbon, hydrogen, sulphur
B. carbon, hydrogen, nickel
C. carbon, hydrogen, manganese
D. carbon, hydrogen, boron

Answer

To determine which of the given options contains macronutrients, we need to first understand what macronutrients are and identify them from the options provided.

### Step-by-Step Solution:

1. **Define Macronutrients**: Macronutrients are essential mineral nutrients required by plants in larger quantities, typically more than 10 mMol per kg of dry matter. They play crucial roles in the synthesis of organic molecules.

2. **List of Macronutrients**: The nine essential macronutrients for plants are:
- Carbon (C)
- Hydrogen (H)
- Oxygen (O)
- Nitrogen (N)
- Phosphorus (P)
- Sulfur (S)
- Potassium (K)
- Calcium (Ca)
- Magnesium (Mg)

3. **Analyze the Options**:
- **Option A**: Carbon-Hydrogen-Sulfur
- All three are macronutrients.
- **Option B**: Carbon-Hydrogen-Nickel
- Nickel is a micronutrient, so this option is not correct.
- **Option C**: Carbon-Hydrogen-Manganese
- Manganese is also a micronutrient, so this option is not correct.
- **Option D**: Carbon-Hydrogen-Boron
- Boron is a micronutrient, so this option is not correct.

4. **Conclusion**: The only option that contains macronutrients is **Option A: Carbon-Hydrogen-Sulfur**.

### Final Answer:
**The macronutrients from the options provided are: Carbon, Hydrogen, and Sulfur (Option A).**
