Options
- A(A)-(I), (B)-(III), (C)-(IV), (D)-(II)
- B(A)-(III), (B)-(I), (C)-(IV), (D)-(II)
- C(A)-(III), (B)-(I), (C)-(II), (D)-(IV)
- D(A)-(III), (B)-(IV), (C)-(I), (D)-(II)
Correct answer
B. (A)-(III), (B)-(I), (C)-(IV), (D)-(II)
Step-by-step solution
According to NCERT, microbes are used for commercial and industrial production of certain chemicals like organic acids. Aspergillus niger (a fungus) is used for the production of citric acid. Acetobacter aceti (a bacterium) is used for the production of acetic acid. Clostridium butylicum (a bacterium) is used for the production of butyric acid. Lactobacillus (a bacterium) is used for the production of lactic acid. Therefore, the correct match is (A)-(III), (B)-(I), (C)-(IV), (D)-(II). Answer: (A)-(III), (B)-(I), (C
