The component of blood responsible for transporting `O_(2)` is

Options

A. RBC
B. WBC
C. Platelets
D. All of these

Answer

To solve the question regarding which component of blood is responsible for transporting oxygen, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Components of Blood**:
- Blood consists of several components, primarily red blood cells (RBCs), white blood cells (WBCs), and platelets.

2. **Understand the Function of Each Component**:
- **Red Blood Cells (RBCs)**: These cells are primarily responsible for the transport of oxygen. They contain hemoglobin, a protein that binds to oxygen in the lungs and carries it to tissues throughout the body.
- **White Blood Cells (WBCs)**: These cells are part of the immune system and help protect the body against infections. They do not play a role in oxygen transport.
- **Platelets**: These are involved in blood clotting and help prevent excessive bleeding. They also do not transport oxygen.

3. **Focus on the Role of Hemoglobin**:
- Hemoglobin, found in RBCs, has a high affinity for oxygen, allowing it to pick up oxygen in the lungs and release it in tissues where it is needed.

4. **Conclude the Answer**:
- Since RBCs are the only component that transports oxygen due to the presence of hemoglobin, the correct answer to the question is **Red Blood Cells (RBCs)**.

### Final Answer:
The component of blood responsible for transporting \( O_2 \) is **Red Blood Cells (RBCs)**.
