The group of mineral nutrients known as frame work elements is

Options

A. N, S, P
B. C, H, O
C. Mg, Fe, Zn
D. Zn, Mn, Cu

Answer

To answer the question regarding the group of mineral nutrients known as framework elements, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Framework Elements**:
- Framework elements are essential components that contribute to the structure and stability of plant cells, particularly in the formation of the cell wall.

2. **Identify the Major Component of the Cell Wall**:
- The primary component of the cell wall in plants is cellulose. Cellulose is a polysaccharide made up of glucose units and is crucial for providing structural support to the plant.

3. **Determine the Elements Involved in Cellulose Formation**:
- Cellulose is primarily composed of three elements: carbon (C), hydrogen (H), and oxygen (O). These elements are integral to the molecular structure of cellulose.

4. **Evaluate the Options Provided**:
- The options given include:
- Nitrogen, Sulphur, Phosphorus, Carbon, Hydrogen, Oxygen, Magnesium, Iron, and Zinc
- Zinc, Magnesium, and Copper
- Among these, the elements that are directly involved in the formation of cellulose (and thus the framework of the plant cell) are carbon, hydrogen, and oxygen.

5. **Conclude the Answer**:
- Therefore, the group of mineral nutrients known as framework elements is **Carbon, Hydrogen, and Oxygen**.

### Final Answer:
The group of mineral nutrients known as framework elements is **Carbon, Hydrogen, and Oxygen**.
