• A. Heart
• B. Skin
• C. Liver
• D. Brain

Answer: (B)

The largest organ of the body is the skin. It serves as a protective barrier covering the entire body and plays a vital role in various physiological functions. The skin regulates body temperature, allows for the sensation of touch, and acts as a first line of defense against pathogens and environmental hazards.

In adults, the skin can weigh between 8 to 10 pounds and account for approximately 15% of a person's total body weight. Its extensive surface area and complex structure, which includes multiple layers and components, further underscore its significance as the largest organ. Understanding the role and importance of the skin is essential in fields such as dermatology and cosmetology, especially for nail technicians who must be aware of skin care and nail health.
