Carry impulses from the brain to muscles or glands

• A. Sensory nerves/ Afferent nerves
• B. Interneurons
• C. Motor nerves/ efferent nerves
• D. Mixed nerves

Answer: (C)

The main idea here is the type of nerve that carries signals from the brain to the muscles or glands to produce action. That job is done by motor nerves, also called efferent nerves. They take commands from the central nervous system and deliver them to effectors like muscles to cause movement or to glands to trigger secretions.

Sensory (afferent) nerves, by contrast, carry signals from the body back to the brain. Interneurons stay within the brain and spinal cord and connect other neurons. Mixed nerves contain both sensory and motor fibers, but the question specifies impulses going from the brain to muscles or glands, which is the role of motor/efferent nerves.
