Concept: This question tests your understanding of the basic divisions and functions of the nervous system, specifically the role of afferent nerve fibers in the Peripheral Nervous System (PNS).

Why (C) is correct: Afferent nerve fibers (also known as sensory neurons) are responsible for carrying sensory information from various tissues, organs, and sensory receptors in the body towards the Central Nervous System (CNS). This allows the CNS to receive information about the internal and external environment.

Why other options are wrong:

• (A) Transmitting impulses from the CNS to skeletal muscle: This is the function of somatic efferent (motor) nerve fibers.
• (B) Transmitting impulses from the CNS to involuntary organs: This is the function of autonomic efferent (motor) nerve fibers.
• (D) Transmitting impulses from the tissue/organ to heart only: Afferent fibers transmit impulses to the CNS from all tissues and organs, not just the heart.

Common Mistake: Students often confuse afferent (sensory) and efferent (motor) pathways. Remember the direction of information flow.

NEET Tip / Mnemonic: Remember "SAME DAVE": Sensory Afferent, Motor Efferent. Also, Dorsal Afferent, Ventral Efferent (referring to spinal cord roots).

Correct Answer: (C)
