A. Induces formation of antigen
B. Helps in production of WBC
C. Is formed by WBC
D. None of the above

Answer

**Step-by-Step Solution:**

1. **Understanding Antibodies**: Antibodies are large Y-shaped proteins known as immunoglobulins. They play a crucial role in the immune system by identifying and neutralizing foreign objects like bacteria and viruses.

2. **Source of Antibodies**: Antibodies are produced by B lymphocytes, which are a type of white blood cell (WBC). This is an essential aspect of the adaptive immune response.

3. **Analyzing the Options**:
- **Option A**: "Induces the formation of antigen" - This is incorrect. Antigens are substances that induce the formation of antibodies, not the other way around.
- **Option B**: "Helps in the production of WBCs" - This is also incorrect. WBCs (including B lymphocytes) are responsible for producing antibodies, not the other way around.
- **Option C**: "It is formed by WBC" - This statement is correct as antibodies are indeed formed by B lymphocytes, which are a type of WBC.
- **Option D**: "None of the above" - This is incorrect because we have already established that option C is a correct statement.

4. **Conclusion**: Based on the analysis of the options, the correct answer is **C: It is formed by WBC**.
