None of the above mentioned animals have five hearts.
So, the answer will be option 4. None of these.
The earthworm has five hearts.
If we follow the dorsal vessel anteriorly of the earthworms to the esophagus then we could find the five pairs of large, contractile, segmental blood vessels.
They are referred to as hearts of the earthworm.
