Question

Cestodes are distinguished from other flatworms by the absence of:

• A. Nervous system
• B. Digestive system
• C. Excretory system
• D. Reproductive system

Answer 1

The correct option is B Digestive system

Cestodes are endoparasites seen inside the intestines of vertebrates. A common example is Taenia. As these animals absorb pre-digested food available in the intestine, the digestive system is absent in these animals.

So, the correct option is B.
