Question

Match List-I with List-II:

List-I (Function)	List-II (Organism)
(A) Nitrogen fixation (bacterium)	(I) Saccharomyces
(B) Phosphorous absorption	(II) Azospirillum
(C) Nitrogen fixation (cyanobacterium)	(III) Glomus
(D) Ethanol Production	(IV) Oscillatoria

• A. (A)-(II), (B)-(I), (C)-(IV), (D)-(III)
• B. (A)-(II), (B)-(IV), (C)-(I), (D)-(III)
• C. (A)-(III), (B)-(IV), (C)-(II), (D)-(I)
• D. (A)-(IV), (B)-(III), (C)-(II), (D)-(I)

Answer 1

The Correct Option is A

Let's match the functions with their respective organisms:

(A) Nitrogen fixation (bacterium): Azospirillum is a bacterium known for nitrogen fixation in the soil, especially in association with plant roots. So, (A)-(II) is correct.

(B) Phosphorus absorption: Saccharomyces is a yeast that can absorb phosphorus from the environment. Thus, (B)-(I) is correct.

(C) Nitrogen fixation (cyanobacterium): Oscillatoria is a cyanobacterium that can fix nitrogen in aquatic environments. So, (C)-(IV) is correct.

(D) Ethanol Production: Glomus is a genus of fungi that is involved in the process of ethanol production, often through fermentation. So, (D)-(III) is correct.

Thus, the correct answer is (1) (A)-(II), (B)-(I), (C)-(IV), (D)-(III).
