• C. a-ii, b-iii, c-iv, d-i
• D. a-i, b-iv, c-iii, d-i

Hint:

Penicillium revolutionized medicine with antibiotics, while Anabaena contributes to nitrogen cycling in ecosystems.

Answer 1

The Correct Option is C

• Definition of Matching: The task is to pair each organism in Column-I with its correct biological function or product in Column-II.
• Option Analysis:
  • (a) Streptococcus: Known for producing streptokinase, used as a "clot buster" in medicine. Matches with ii) Clot buster.
  • (b) Penicillium: This fungus is the source of the antibiotic penicillin. Matches with iii) Source of antibiotic.
  • (c) Methanogens: These archaea produce methane gas during anaerobic decomposition, used in biogas production. Matches with iv) Biogas production.
  • (d) Anabaena: A cyanobacterium that performs free-living nitrogen fixation. Matches with i) Free living nitrogen fixing bacteria.
• Correct Pairing: The correct matching is a-ii, b-iii, c-iv, d-i, which corresponds to option (3).
• Conclusion: The correct answer is (3) a-ii, b-iii, c-iv, d-i, as it accurately aligns each organism with its function.
