Correct Answer: Amoeba
Solution : The correct option is Amoeba.
Amoebas do not have a nervous system. Amoebas are unicellular organisms that belong to the group of protists. They are simple, single-celled organisms without specialized tissues or organs. Instead of a nervous system, amoebas rely on more primitive mechanisms to sense and respond to their environment. They possess a flexible cell membrane that allows them to change shape and move through a process called amoeboid movement. This movement is driven by the flow of cytoplasm within the cell.
