The Question
A patient who recently underwent a kidney transplant is prescribed a specific fungal secondary metabolite to prevent graft rejection. Which of the following statements regarding this bioactive molecule and its source organism is INCORRECT?
Options
- A.
The molecule is Cyclosporin A, which acts as an immunosuppressive agent by inhibiting T-cell activation.
- B.
The source organism is Trichoderma polysporum, which belongs to a class of fungi that reproduce asexually via conidia.
- C.
The bioactive molecule prevents graft rejection by primarily suppressing the humoral immune response mediated by B-lymphocytes.
- D.

Why This Question Is Tricky
Common Mistakes
Conceptual Pivot: Integrating 'Microbes in Human Welfare' with 'Human Health and Disease'.
Students often memorize that Cyclosporin A is an 'immunosuppressant' but fail to connect it to the specific type of immunity responsible for graft rejection (Cell-Mediated Immunity via T-cells, not Humoral Immunity via B-cells).
The question also tests cross-chapter taxonomic integration with 'Biological Classification'.
