Answer: (C)

Verified step by step guidance

1. Step 1: Understand the role of the nervous system in communication. The nervous system transmits information throughout the body to coordinate actions and responses.
2. Step 2: Recognize that communication in the nervous system primarily involves neurons, which send signals using electrical impulses and chemical neurotransmitters.
3. Step 3: Differentiate between the nervous system and the endocrine system. The nervous system uses fast electrical and chemical signaling, while the endocrine system uses slower hormonal messages.
4. Step 4: Note that communication in the nervous system is not limited to voluntary muscle movements; it also controls involuntary actions and processes sensory information.
5. Step 5: Understand that communication in the nervous system is not restricted to spoken or written language, as it operates through neural signals rather than verbal or written forms.
