Answer
A is True and R is False.
Reason — The skin is the largest sense organ of the human body. It contains sensory receptors for detecting pressure, pain, heat, and cold, playing a vital role in touch and temperature sensation.
The skin does help protect the body against mechanical, thermal, and physical injury and aids in perspiration but skin is not an organ of the nervous system.
