Correct Answer: Cnidarian

Solution : The correct option is Cnidarian.

Cnidarians, such as jellyfish and corals, are examples of animals that do not have bilateral symmetry. Instead, they typically exhibit radial symmetry, meaning their body parts are arranged in a circular or radial pattern around a central point rather than having a distinct left and right side. This radial symmetry allows them to capture prey and interact with their environment in all directions equally.
