Find out the wrongly matched pair

Options

A. Cnidoblast-Anchorage
B. Parapodia-Defense
C. Parapodia-Swimming
D. Radula-Rasping organ

Answer

To solve the question of finding the wrongly matched pair, we will analyze each option provided.

### Step-by-Step Solution:

1. **Analyze the first option: Nidoblast Anchorage**
- Nidoblasts are specialized cells found in cnidarians (like jellyfish and corals).
- Their primary functions include defense against predators and capturing prey, as well as providing anchorage (attachment to surfaces).
- Since both functions mentioned (defense and anchorage) are accurate, this option is correctly matched.

2. **Analyze the second option: Parapodia Defense**
- Parapodia are bristle-like structures found in annelids, particularly in polychaete worms.
- Their main function is locomotion (movement), specifically aiding in swimming.
- The mention of "defense" is incorrect, as parapodia do not serve a defensive function. Therefore, this option is wrongly matched.

3. **Analyze the third option: Parapodia Swimming**
- As established, parapodia are indeed involved in movement and swimming in annelids.
- This pairing is correct, as it accurately describes the function of parapodia.

4. **Analyze the fourth option: Radula Rasping Organ**
- The radula is a specialized feeding organ found in mollusks.
- It functions as a rasping organ, helping to scrape or tear food.
- This pairing is also correct, as it accurately reflects the function of the radula.

### Conclusion:
The wrongly matched pair is **Parapodia Defense** (Option 2).
