Which one causes degradation of RBC ?

Options

A. Hydrocarbons
B. Sulphur compounds
C. Ammonia
D. Arsenic compound.

Answer

To solve the question "Which one causes degradation of RBC?" we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Options**: The options provided are:
- Hydrocarbons
- Sulfur compounds
- Ammonia
- Arsenic compounds

2. **Understand the Context**: We need to determine which of these substances is known to cause degradation or destruction of red blood cells (RBCs).

3. **Analyze Each Option**:
- **Hydrocarbons**: Generally, hydrocarbons are organic compounds that do not directly cause RBC degradation.
- **Sulfur Compounds**: While some sulfur compounds can be toxic, they are not primarily known for degrading RBCs.
- **Ammonia**: Ammonia can be toxic at high levels but is not specifically known for RBC degradation.
- **Arsenic Compounds**: Arsenic, particularly in its simplest form (arsine), is known to bind with hemoglobin in RBCs, leading to their destruction.

4. **Conclude**: Based on the analysis, arsenic compounds are the ones that cause degradation of RBCs. They bind to hemoglobin, disrupt ATP production, and inhibit important metabolic processes, leading to the destruction of red blood cells.

5. **Final Answer**: Arsenic compounds cause degradation of RBCs.
