Final answer:
General visceral efferent fibers innervate internal organs and glands, controlling involuntary functions such as heart rate, digestion, and glandular secretion. The correct answer is C) Internal Organs and Glands.
Step-by-step explanation:
The general visceral efferent (GVE) fibers are part of the autonomic nervous system and are responsible for providing innervation to internal organs and glands. These motor fibers control involuntary functions such as heart rate, digestion, and glandular secretion. Therefore, the correct answer to the question, 'General visceral efferent fibers provide innervation to which of the following?' is C) Internal Organs and Glands. These fibers are crucial for maintaining homeostasis within the body by regulating the function of various internal organs and involuntary muscles.
