Best answer

Answer: 4. A-III, B-I, C-IV, D-II

Key idea: match each microbe with the product it yields.

  • Clostridium butylicum makes butyric acid (A-III).
  • Saccharomyces cerevisiae ferments sugar to ethanol (B-I).
  • Trichoderma polysporum produces cyclosporin-A, an immunosuppressant (C-IV).
  • Streptococcus produces streptokinase, a clot buster (D-II).

This gives A-III, B-I, C-IV, D-II.
