Monoclonal antibodies are

Options

A. Obtained from a cell and act on one antigen
B. Obtained from a group of cells and act on more than one antigens
C. Obtained from a group of same type of cells and act on single antigen
D. Obtained from a group of same type of cells and act on more than one antigens

Explanation

**Step-by-Step Solution:**

1. **Understanding Monoclonal Antibodies**:
Monoclonal antibodies are antibodies that are identical and produced from a single clone of cells. They are designed to bind to a specific antigen.

2. **Analyzing the Options**:
- **Option A**: "Obtained from a cell and act on one antigen" - This is partially correct but lacks the specificity of being from a clone.
- **Option B**: "Obtained from a group of cells and act on more than one antigen" - This describes polyclonal antibodies, not monoclonal.
- **Option C**: "Obtained from a group of same type of cells and act on single pattern" - This is correct as monoclonal antibodies are derived from a single clone of cells and target a specific antigen.
- **Option D**: "Obtained from a group of same type of cells and act on more than one antigen" - Again, this describes polyclonal antibodies.

3. **Identifying the Correct Answer**:
Based on the analysis, the correct answer is **Option C**: "Obtained from a group of same type of cells and act on single pattern".

4. **Conclusion**:
Monoclonal antibodies are specialized antibodies that are produced from a single type of cell and are specific to one type of antigen, making them highly effective in various applications, including diagnostics and therapeutics.
