B. This nutrient is the component of the nitrate radical enzyme.
C. This nutrient is required for the photolysis of water .

Options

A. A : Cu , B : Zn, C : Cl
B. A : Zn , B : Mo , C,Cl
C. A : B , B : Mo , C: Mn
D. A : Fe , B : Cu , C : Mn

Answer

To solve the question, we need to identify the nutrients based on the descriptions provided for A, B, and C.

### Step-by-Step Solution:

1. **Identify Nutrient A**:
- The statement says, "This nutrient helps in the utilization of calcium."
- The nutrient that assists in the utilization of calcium is **Boron (B)**. Boron plays a crucial role in cell wall synthesis and cell division in plants, especially when combined with calcium.

2. **Identify Nutrient B**:
- The statement says, "This nutrient is the component of the nitrate radical enzyme."
- The nutrient that is a component of the nitrate radical enzyme is **Molybdenum (Mo)**. Molybdenum is essential for the conversion of nitrate to nitrite and then to ammonia, which is critical for nitrogen metabolism in plants.

3. **Identify Nutrient C**:
- The statement says, "This nutrient is required for the photolysis of water."
- The nutrient that is required for the photolysis of water (the process of breaking down water molecules during photosynthesis) is **Manganese (Mn)**. Manganese is involved in the oxygen-evolving complex of photosystem II, which is essential for the release of oxygen during photosynthesis.

### Final Answer:
- A: Boron (B)
- B: Molybdenum (Mo)
- C: Manganese (Mn)
