The correct Answer is:
### Step-by-Step Solution: 1. **Understand the Structure and Function of Radula**: - Radula is a specialized feeding organ found in many molluscs. It is often described as a rasping organ that helps in scraping or cutting food before it enters the digestive tract. 2. **Identify the Characteristics of Molluscs**: - Molluscs belong to the second largest phylum in the animal kingdom. They are characterized by soft bodies, which are often protected by a hard shell. 3. **Evaluate the Statements Regarding Radula**: - The question asks to consider various statements about the radula. We need to determine which statement is correct. - **Statement 1**: "Radula is a phyle-like rasping organ." This statement is correct as it accurately describes the radula's function. - **Statement 2**: "Radula is a mouth-like sucking organ." This statement is incorrect because the radula is not used for sucking; it is used for rasping. - **Statement 3**: "Radula is an excretory organ." This statement is also incorrect as the radula does not play a role in excretion. - **Statement 4**: Any other statement that might be presented should also be evaluated similarly. 4. **Conclusion**: - After evaluating the statements, we find that only Statement 1 is correct regarding the radula of molluscs. The other statements are incorrect.
