The central nervous system is lacking in animals that have radial symmetry.
<h3>What is meant by the central nervous system?</h3>
Animals with radial symmetry do not have a central nervous system. The brain and spinal cord make up the central nervous system (CNS). The CNS's three major functions are to receive sensory information, process information, and send out motor signals. The CNS receives sensory information from the nervous system and directs the responses of the body.
The central nervous system is the processing center of the body. The brain is in charge of the majority of the body's functions, including awareness, movement, thinking, speech, and the five senses of seeing, hearing, feeling, tasting, and smelling. The spinal cord is a brain extension.
Therefore, the correct answer is option C. radial symmetry.
