(b) Statins produced by the yeast Monascus purpureus are blood-cholesterol lowering agents ⇒ (iv).

(c) Cyclosporin A, produced by the fungus Trichoderma polysporum, is an immunosuppressive agent used in organ-transplant patients ⇒ (i).

(d) The large holes in Swiss cheese are due to production of a large amount of CO2 by Propionibacterium sharmanii ⇒ (ii).

∴ (a) - (iii), (b) - (iv), (c) - (i), (d) - (ii).

The domestic sewage in large cities :

  1. has very high amounts of suspended solids and dissolved salts
