Deficiency of copper causes

Options

A. Anaemia and damage to CNS
B. Xerophthalmia
C. Pellagra
D. Influenza.

Answer

**Step-by-Step Solution:**

1. **Understanding the Role of Copper:**
- Copper is a trace mineral essential for various physiological functions in the human body. It plays a critical role in the maturation of red blood cells (RBCs), maintenance of nerve cells, immune system function, collagen production, ATP formation, and iron absorption.

2. **Analyzing the Options:**
- The question provides four options regarding the consequences of copper deficiency:
- A) Anemia and damage to CNS
- B) Xerophthalmia
- C) Pellagra
- D) Influenza

3. **Evaluating Each Option:**
- **Option A: Anemia and damage to CNS**
- Since copper is necessary for the maturation of RBCs, a deficiency could lead to reduced RBC production, resulting in anemia. Additionally, copper is vital for maintaining nerve cells, so its deficiency could also damage the central nervous system (CNS). This option is likely correct.

- **Option B: Xerophthalmia**
- Xerophthalmia is a condition caused by a deficiency of vitamin A, not copper. Therefore, this option is incorrect.

- **Option C: Pellagra**
- Pellagra is caused by a deficiency of vitamin B3 (niacin). It is unrelated to copper deficiency, making this option incorrect.

- **Option D: Influenza**
- Influenza is a viral infection and is not associated with copper deficiency. Thus, this option is also incorrect.

4. **Conclusion:**
- After evaluating all options, the correct answer is **Option A: Anemia and damage to CNS**, as these conditions are directly linked to the deficiency of copper.
