Question

Match Column-I with Column-II and choose the correct option given below:

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

Hint:

Bacterial shapes like coccus (spherical) and bacillus (rod-shaped) are key for identification.

Answer 1

The Correct Option is D

• Bacterial Shapes:
  • Coccus: Spherical
  • Bacillus: Rod-shaped
  • Vibrium: Comma-shaped
  • Spirillum: Spiral
• Matching Analysis:
  • (a) Coccus → (iii) Spherical
  • (b) Bacillus → (i) Rod-shaped
  • (c) Vibrium → (iv) Comma-shaped
  • (d) Spirillum → (ii) Spiral
• Option Analysis:
  • (1) a-iii, b-ii, c-iv, d-i: Matches correctly.
  • (2) a-iv, b-ii, c-i, d-iii: Incorrect matches.
  • (3) a-iv, b-i, c-ii, d-iii: Incorrect matches.
  • (4) a-iii, b-i, c-iv, d-ii: Matches correctly.
• Conclusion: Option (4) correctly matches the bacterial shapes.
