Classification (biology – body parts): Three pairs are mismatched organism→structure; one pair is correctly matched. Identify the correctly matched pair.

Introduction / Context:
Biology classification can invert the usual pattern by asking for the only correct mapping among several incorrect ones. Here, three organism→structure pairs are wrong, while one is right. The task is to find the correctly matched pair.

Given Data / Assumptions:

• Hydra has tentacles used for food capture and limited locomotion.
• Plasmodium (malarial parasite) does not use cilia for movement; it exhibits gliding/amoeboid movement depending on life stage.
• Lizards do not possess flagella; flagella are microscopic appendages (e.g., in certain cells or microorganisms).
• Cockroach body bears antennae (spelled “antennae”), which are sensory, not listed here correctly due to spelling (“Anternae”).

Concept / Approach:
Validate the existence/appropriateness of the named structure for the given organism. Select the sole accurate pair even if another pair contains a misspelling (antennae) because Hydra : Tentacles is unambiguously correct without caveats.

Step-by-Step Solution:

Verification / Alternative check:
Cross-reference basic zoology: Hydra is a cnidarian with tentacles bearing nematocysts; this is standard textbook knowledge.

Why Other Options Are Wrong:

Common Pitfalls:
Overlooking that the question asks for the correctly matched pair among several incorrect/malformed ones.

Final Answer:
Hydra : Tentacles
