With reference to monoclonal antibodies, often mentioned in news, consider the following statements : 1. They are man-made proteins. 2. They stimulate immunological function due to their ability to bind to specific antigens. 3. They are used in treating viral infections like that of Nipah virus. Which of the statements given above are correct?

All three statements are correct because monoclonal antibodies (mAbs) are laboratory-produced proteins designed to bind to specific antigens to neutralize pathogens or trigger an immune response, and they are used in treating viral diseases like Nipah (e.g., the m102.4 antibody). Option (a) is the most tempting wrong choice for candidates who might incorrectly assume mAbs only neutralize targets without stimulating broader immunological activity or that their use is limited to cancer treatment. The core concept tested is the therapeutic mechanism and clinical application of biotechnology in modern immunology.
