⏱️ Save ~30 seconds

Clostridium butylicum -> Butyric acid (III). Streptococcus -> Streptokinase (II). Direct two-point confirmation locks Option (1)!

1 A. Clostridium butylicum -> III. Butyric acid (name gives it away!).
2 B. Saccharomyces cerevisiae -> I. Ethanol (Brewer’s yeast).
3 C. Trichoderma polysporum -> IV. Cyclosporin-A (immunosuppressive agent).
4 D. Streptococcus -> II. Streptokinase ("clot buster").
5 Matching order: A-III, B-I, C-IV, D-II -> Option (1) / A.

Step-by-Step Rigorous Workflow & Mathematical Proof

Step 1

Match Industrial Fermentation Products

Clostridium butylicum is a bacterium that ferments substrates to produce butyric acid (A -> III). Saccharomyces cerevisiae (Brewer’s yeast) ferments malted cereals and fruit juices to produce ethanol (B -> I).

Step 2

Match Bioactive Molecules and Enzymes

Trichoderma polysporum (fungus) produces Cyclosporin-A, an immunosuppressive agent used in organ-transplant patients (C -> IV). Streptococcus produces streptokinase, modified by genetic engineering and used as a "clot buster" to remove clots from blood vessels of patients suffering from myocardial infarction (D -> II).

Step 3

Assemble Combination

The unique valid combination is A-III, B-I, C-IV, D-II, corresponding to Option (1).

Mismatches Clostridium with Cyclosporin-A and Trichoderma with Butyric acid.

⚠️
Student Fallacy (Why candidates pick this trap): Mismatches Clostridium with Cyclosporin-A and Trichoderma with Butyric acid.
4 (4)
✗ Incorrect
Verdict & Scientific Reason:

Mismatches Saccharomyces with Cyclosporin-A and Streptococcus with Ethanol.

⚠️
Student Fallacy (Why candidates pick this trap): Mismatches Saccharomyces with Cyclosporin-A and Streptococcus with Ethanol.

NTA Trap Alert: Cyclosporin-A vs Statins Producer

Confusing Trichoderma polysporum (Cyclosporin-A) with Monascus purpureus (Statins).

🛡️ How to avoid the -1 mark: Remember: Trichoderma = Cyclosporin-A; Monascus = Statin.
