| List-I | List-II | ||
| (a) | Aspergillus niger | (i) | Acetic Acid |
| (b) | Acetobacter aceti | (ii) | Lactic Acid |
| (c) | Clostridium butylicum | (iii) | Citric Acid |
| (d) | Lactobacillus | (iv) | Butyric Acid |
(iv) (ii) (i) (iii)
(iv) (ii) (i) (iii)
(i) (ii) (iii) (iv
(ii) (iii) (i) (iv)
To solve this problem, we need to correctly match the microorganisms in List-I with the acids they produce or are associated with in List-II.
By using the information above, we can match each organism from List-I to their respective product in List-II:
Therefore, the correct matches are: (iv) (ii) (i) (iii), which corresponds to the option: (iv) (ii) (i) (iii).
Hence, the correct answer is the choice (iv) (ii) (i) (iii). This matches each organism in List-I with its correct acid product in List-II.

Biotechnology is a vast field of biology that involves the creation, production, and modification of useful products for human welfare using both the technology and the execution of living organisms and their components. An agricultural engineer, Karoly Ereky, coined the word "biotechnology" in 1919, achieving him the title of "Father of Biotechnology."
Among many, the two core techniques that entitled the birth of modern biotechnology are :
