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'.

Answer:
The correct matching pair of a body feature and the animal possessing it is option 'A': Ventral central - Leech nervous system.
Explanation:
To determine the correct matching pair, let's analyze each option:
a) Ventral central - Leech nervous system:
Leeches have a ventral central nervous system. The ventral central nervous system consists of a chain of ganglia located along the ventral side of the leech's body. This nervous system allows leeches to coordinate their movements and respond to stimuli in their environment.
b) Pharyngeal gill slits - Chameleon absent in embryo:
Chameleons do not possess pharyngeal gill slits. Pharyngeal gill slits are present in aquatic organisms such as fish and are used for respiration. Chameleons, being terrestrial animals, do not have gill slits in any stage of their development.
c) Ventral heart - Scorpion:
Scorpions do not have a ventral heart. Instead, they have a dorsal heart located in the abdomen. The dorsal heart pumps hemolymph (a fluid similar to blood in other animals) throughout the scorpion's body.
d) Post-end tail - Octopus:
Octopuses do not have a post-end tail. Octopuses belong to a group of animals called cephalopods, which have a unique body plan that includes a soft body with a mantle, a head with eyes and arms, and no distinct tail.
Therefore, the correct matching pair is option 'A': Ventral central - Leech nervous system. Leeches have a ventral central nervous system consisting of ganglia along their ventral side.
