Options

A. Ca, Mg, K , Na
B. Cu, Fe, Mg, Mn, Mo
C. C, H, O, N, S, F
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding Catalytic Functions**: Catalytic functions refer to the processes that speed up chemical reactions in living organisms, including plants. These functions are essential for various biochemical processes.

2. **Identifying Key Elements**: In plants, certain elements play a crucial role in facilitating these catalytic functions. These elements are often referred to as micronutrients or trace elements.

3. **Listing the Elements**: The key elements that are known to control catalytic functions in plants include:
- **Copper (Cu)**: Acts as a cofactor for various enzymes.
- **Iron (Fe)**: Essential for chlorophyll synthesis and acts as a cofactor in many enzymatic reactions.
- **Magnesium (Mg)**: Central atom in chlorophyll and is involved in many enzymatic reactions.
- **Manganese (Mn)**: Plays a role in photosynthesis and is a cofactor for several enzymes.
- **Molybdenum (Mo)**: Important for nitrogen fixation and enzyme function.

4. **Conclusion**: Therefore, the elements that control catalytic functions in plants include Copper, Iron, Magnesium, Manganese, and Molybdenum.

**Final Answer**: Catalytic functions are controlled by elements like Copper (Cu), Iron (Fe), Magnesium (Mg), Manganese (Mn), and Molybdenum (Mo).
