please select the best answer from the choices provided
a
b
c
d

Explanation:

Nerves are part of the nervous system. They are responsible for carrying two types of impulses - sensory impulses (which carry information from sensory organs like eyes, ears, skin to the central nervous system) and motor impulses (which carry information from the central nervous system to muscles and glands).

• Option A is too vague as it just says "send information" without specifying the nature of the information.
• Option B is incorrect because while some nerves (like spinal nerves) connect the brain (and spinal cord) to the body, this is not the comprehensive function of all nerves.
• Option C is also incorrect as it only mentions carrying messages from muscles (motor aspect) but ignores the sensory aspect.

Answer:

D. They carry sensory and motor impulses.
