This question was posed to me during an online exam.

This interesting question is from Classification of Animal Kingdom into Different Phylum-3 in division Animal Kingdom of Biology – Class 11

Answer 1

Correct choice is (c) Dorsal nerves act as sensory nerves of the body

For explanation I would say: Nerve ring made of four ganglia serves as brain. Nerve chords are present on the dorsal and ventral side of their body. Dorsal nerves act as motor nerves of the body. Ventral nerves act as both motor controllers and sensory nerves of the body.
