Mark the correct statement

Options

A. An antibody is represented by H2L4
B. The T-lymphocytes produce antibodies
C. The B-lymphocyte produces cell mediated response
D. The anamnestic response against a pathogen is highly intensified

Answer

To solve the question of marking the correct statement regarding antibodies and lymphocytes, we need to analyze each statement provided.

### Step-by-Step Solution:

1. **Evaluate the First Statement**:
- The statement claims that an antibody is represented by H2L4.
- **Analysis**: This is incorrect because antibodies are actually represented by the formula H2L2, where H stands for heavy chains and L stands for light chains.

2. **Evaluate the Second Statement**:
- The statement claims that lymphocytes produce antibodies.
- **Analysis**: This is partially correct; however, it is important to specify that B lymphocytes produce antibodies, while T lymphocytes are involved in cell-mediated immunity. Therefore, the statement is misleading.

3. **Evaluate the Third Statement**:
- The statement claims that B lymphocytes produce cell-mediated responses.
- **Analysis**: This is incorrect because B lymphocytes are primarily responsible for humoral immunity (producing antibodies), while T lymphocytes are responsible for cell-mediated immunity.

4. **Evaluate the Fourth Statement**:
- The statement claims that the anaesthetic response is highly intensified.
- **Analysis**: This statement is correct. The anaesthetic response can indeed be intensified, which is a valid observation in the context of immune responses.

### Conclusion:
- The correct statement among the provided options is the fourth statement: "the anaesthetic response is highly intensified."
