The blood groups will have their respective anti bodies in the

Options

A. RBC
B. WBC
C. Plasma
D. Thrombocytes

Answer

To answer the question "The blood groups will have their respective antibodies in the", we need to analyze the components of blood and where antibodies are located. Here’s a step-by-step solution:

### Step 1: Understand Blood Groups
There are four main blood groups in humans: A, B, AB, and O. Each blood group has specific antigens on the surface of red blood cells (RBCs) and corresponding antibodies in the plasma.

### Step 2: Identify Antigens and Antibodies
- **Blood Group A**: Has antigen A on RBCs and produces anti-B antibodies in the plasma.
- **Blood Group B**: Has antigen B on RBCs and produces anti-A antibodies in the plasma.
- **Blood Group AB**: Has both antigen A and antigen B on RBCs and does not produce any antibodies against A or B.
- **Blood Group O**: Has no antigens on RBCs and produces both anti-A and anti-B antibodies in the plasma.

### Step 3: Determine the Location of Antibodies
Antibodies are proteins that are found in the plasma component of blood. They are not found in red blood cells (RBCs), white blood cells (WBCs), or thrombocytes (platelets).

### Step 4: Analyze the Options
Now, we will analyze the options given in the question:
1. **RBCs**: Incorrect, as RBCs contain antigens, not antibodies.
2. **WBCs**: Incorrect, as WBCs are involved in immune response but do not contain specific blood group antibodies.
3. **Plasma**: Correct, as this is where the antibodies corresponding to the blood groups are found.
4. **Thrombocytes**: Incorrect, as thrombocytes are involved in clotting and do not contain antibodies.

### Conclusion
The correct answer is **plasma**, as it is the component of blood that contains the respective antibodies for the blood groups.
