A. Cyclosporin A is a bioactive molecule that is widely used as an immunosuppressive agent in organ transplant patients. It plays a crucial role in preventing organ rejection by suppressing the immune system's response to the transplanted organ. This important medication is derived from the fungus Trichoderma polysporum.

B. Streptokinase, produced by the bacterium Streptococcus and genetically modified, serves as a "clot buster" in the removal of blood clots from the vessels of individuals who have experienced a heart attack.

C. Aspergillus niger is a fungus known for its ability to produce citric acid. It is widely used in the food and beverage industry for the production of citric acid, which is commonly used as a flavoring agent and preservative.
