Muscles contains a red coloured oxygen storing pigment called `:-`

Options

A. Haemoglobin
B. myoglobin
C. erythrocruorin
D. haemolymph

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the name of the red-colored oxygen-storing pigment found in muscles.

2. **Analyzing the Options**:
- **Hemoglobin**: This is a protein found in red blood cells that transports oxygen from the lungs to the rest of the body. It is not specifically an oxygen-storing pigment in muscles.
- **Myoglobin**: This is a red-colored protein found in muscle tissue that stores oxygen for use during muscle contraction. It is specifically adapted for this function.
- **Erythrofuranin**: This is a respiratory pigment found in some invertebrates, but it is not relevant to muscle tissue in vertebrates.
- **Hemolymph**: This is a fluid that functions similarly to blood in invertebrates, but it is not a pigment and does not store oxygen in muscles.

3. **Identifying the Correct Answer**: Based on the analysis, the only option that specifically refers to an oxygen-storing pigment in muscles is **Myoglobin**.

4. **Conclusion**: Therefore, the correct answer to the question is **Myoglobin**.

**Final Answer**: Myoglobin
