C

(a)-(ii), (b)-(iv), (c)-(iii), (d)-(v)

D

(a)-(iii), (b)-(iv), (c)-(v), (d)-(i)

Step-by-Step Solution

According to the text:

  • Aspergillus niger (a fungus) produces Citric acid (ii).
  • Acetobacter aceti (a bacterium) produces Acetic acid (iv).
  • Clostridium butyricum (a bacterium) produces Butyric acid (v).
  • Lactobacillus (a bacterium) produces Lactic acid (iii).
  • Ethanol is produced by Saccharomyces cerevisiae (yeast). Therefore, the correct matching sequence is (a)-(ii), (b)-(iv), (c)-(v), (d)-(iii).
