• B. (a – iv – s), (b – iii – q), (c – ii – r), (d – i – p)
• C. (a – iv – r), (b – iii – p), (c – ii – q), (d – i – s)

Hint:

Understand flagellar structures and appendage arrangements to match algal and protozoan types correctly.

Answer 1

The Correct Option is C

Step 1: Understand List-I organisms.
- a) Cryptomonas: unicellular flagellate algae.
- b) Polytoma: non-photosynthetic green algae.
- c) Euglena: flagellated photosynthetic protozoan.
- d) Monas: simple unicellular flagellate protozoan.

Step 2: List-II terms.
- i) Pantonomic: associated with all body regions.
- ii) Stichonematic: single row of longitudinal microtubules.
- iii) Acronematic: flagellum with terminal filament.
- iv) Anematic: flagellum without terminal filament.

Step 3: List-III characteristics.
- p) 1 row of lateral appendages.
- q) No lateral appendages and terminal filament.
- r) 2 rows of lateral appendages.
- s) Terminal filament.

Step 4: Matching logic.
- Cryptomonas: Anematic (iv), 2 rows of lateral appendages (r).
- Polytoma: Acronematic (iii), 1 row of lateral appendages (p).
- Euglena: Stichonematic (ii), no lateral appendages, terminal filament (q).
- Monas: Pantonematic (i), terminal filament (s).

Step 5: Conclusion.
- Correct combination: (a – iv – r), (b – iii – p), (c – ii – q), (d – i – s).
