Given below are two statements, one labeled as Assertion (A) and the other labeled as Reason (R). **Assertion (A):** Monoclonal antibodies are highly specific because they are produced by a single clone of B-cells and recognize a single epitope on an antigen. **Reason (R):** Monoclonal antibodies are synthesized in vitro by fusing a myeloma cell with a T-lymphocyte. Select the correct answer using the codes given below:

Options:

• A: Both A and R are true and R is the correct explanation of A
• B: Both A and R are true but R is not the correct explanation of A
• C: A is true but R is false
• D: A is false but R is true
