| D. Glomus | IV. Statins |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → A-I, B-IV, C-II, D-III
(A) Immunosuppressive drug — this matches (I) Cyclosporin A. Cyclosporin A is made by the fungus Trichoderma polysporum. It suppresses the immune system, so it is given to organ-transplant patients to stop rejection.
(B) Blood cholesterol lowering agents — this matches (IV) Statins. Statins are made by the yeast Monascus purpureus. They block the enzyme that makes cholesterol, so they lower blood cholesterol.
(C) Sewage treatment — this matches (II) BOD test. BOD is the amount of oxygen bacteria would use to break down the organic matter in one litre of water. A high BOD means highly polluted water, so the BOD test shows how well sewage has been treated.
(D) Glomus — this matches (III) Mycorrhiza. Fungi of the genus Glomus live with plant roots as mycorrhiza. They absorb phosphorus from the soil and pass it to the plant.
