Match the correct option of deficiency symptoms.

Options

A. (a) Cu - exanthema
B. (b) Mg - interveinal chlorosis and upward curling of leaves
C. (c) Zn - malformation of leaves and fruits
D. (d) All of the above

Answer

### Step-by-Step Solution:

1. **Identify the Nutrient Deficiencies**:
- The question requires us to match deficiency symptoms with the correct nutrient (Copper, Magnesium, Zinc).

2. **Copper Deficiency Symptoms**:
- Copper is an immobile nutrient, meaning its deficiency first appears in new leaves.
- Symptoms include:
- **Chlorosis**: Yellowing of leaves due to insufficient chlorophyll.
- **Enzyme thema**: This leads to the production of harmful gum on the bark and affects root bearing capacity.
- **Wilting**: Leaves shed off prematurely.
- **Conclusion**: Copper deficiency causes chlorosis, enzyme thema, and wilting.

3. **Magnesium Deficiency Symptoms**:
- Magnesium is a mobile nutrient, so its deficiency first appears in older leaves.
- Symptoms include:
- **Intervenial chlorosis**: Yellowing between the veins of leaves.
- **Wilting**: Leaves may appear limp.
- **Stunted growth**: Overall growth of the plant is affected.
- **Upward curling of leaves**: Leaves curl upwards as a sign of deficiency.
- **Conclusion**: Magnesium deficiency causes intervenial chlorosis and upward curling of leaves.

4. **Zinc Deficiency Symptoms**:
- Zinc is a micronutrient and its deficiency can lead to:
- **Stunted growth**: Reduced growth of the plant.
- **Malformation of leaves and fruits**: Leaves and fruits may develop abnormally.
- It affects the basic metabolism of plants.
- **Conclusion**: Zinc deficiency causes stunted growth and malformation of leaves and fruits.

5. **Final Conclusion**:
- All three nutrients (Copper, Magnesium, and Zinc) have specific deficiency symptoms.
- Therefore, the correct option that encompasses all these symptoms is **D: All of the above**.
