Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding Cestoda.
Cestoda (tapeworms) are endoparasites that live in the intestine of hosts and require attachment structures.
Step 2: Types of attachment organs.
Different cestodes possess different anchoring structures like hooks, suckers, and bothria.
Step 3: Meaning of bothria.
Bothria are longitudinal grooves or leaf-like sucking structures used for attachment.
Step 4: Evaluating options.
- Hooks: found in some tapeworms but not leaf-like.
- Suckers: circular attachment structures.
- Acetabulum: typical of trematodes, not cestodes.
Step 5: Biological reasoning.
Bothria provide a leaf-like anchoring adaptation in certain cestodes.
Step 6: Final conclusion.
Thus, bothria are correct.
