Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → A-IV, B-I, C-II, D-III
(A) Swiss cheese — this matches (IV) Propionibacterium sharmanii. This bacterium makes a lot of carbon dioxide, and the gas forms the large holes of Swiss cheese.
(B) Biogas — this matches (I) Methanobacterium. It is one of the methanogens. They grow without oxygen on cattle dung and produce methane, the main gas of biogas.
(C) Acetic acid — this matches (II) Acetobacter aceti. This bacterium turns ethanol into acetic acid, which is vinegar.
(D) Butyric acid — this matches (III) Clostridium butylicum. This bacterium ferments sugars to give butyric acid.
