D. Lizard

Check Answer

The correct answer is C. Sponges.
Sponges are aquatic animals that belong to the phylum Porifera. They are multicellular but do not have a nervous system. Instead, they rely on a system of water channels and specialized cells called choanocytes to move water through their bodies and capture food particles. In contrast, bats, squirrels, and lizards all have nervous systems.

The nervous system is a complex network of cells that transmit signals between different parts of the body and is responsible for controlling movement, sensation, and many other functions in animals.
