Answer 1

Answer: (C)

Ventral central nervous system- leech

The heart of scorpion is present in the mid-dorsal region and not in ventrally.

There is no post-anal tail in octopus.

Pharyngeal gill slits are present in the embryo of Chameleon.

Leech possesses a ventral nervous system.

So, the correct answer is 'Ventral central nervous system- leech'.
