The correct Answer is:
To solve the matching question between Column I and Column II, we will analyze each term in Column I and find its corresponding match in Column II. ### Step-by-Step Solution: 1. **Identify Flame Cells (A)**: - Flame cells are specialized excretory structures found in flatworms, particularly in the genus Planaria. - **Match**: A (Flame cells) → R (Planaria) 2. **Identify Collar Cells (B)**: - Collar cells, also known as choanocytes, are characteristic of sponges (phylum Porifera). - **Match**: B (Collar Cells) → P (Sponges) 3. **Identify Stinging Cells (C)**: - Stinging cells, or nematocysts, are found in organisms of the phylum Cnidaria, which includes Hydra. - **Match**: C (Stinging Cells) → Q (Hydra) 4. **Identify Pseudocoelom (D)**: - A pseudocoelom is a body cavity that is not fully lined by mesoderm and is characteristic of the phylum Nematoda (roundworms), with Ascaris being a well-known example. - **Match**: D (Pseudocoelom) → S (Ascaris) ### Final Matches: - A → R (Flame cells → Planaria) - B → P (Collar Cells → Sponges) - C → Q (Stinging Cells → Hydra) - D → S (Pseudocoelom → Ascaris) ### Conclusion: The correct matching is: - A → R - B → P - C → Q - D → S Thus, the answer is the first option. ---
