Answer: C

Explanation:

The largest organ of the body is the skin.

The skin is the largest organ of the human body, serving as a protective barrier and playing a vital role in various physiological processes.

A) liver.

While the liver is a significant organ responsible for many metabolic processes, it is not the largest organ in the body. The liver is smaller in surface area compared to the skin, which envelops the entire body.

B) kidney.

The kidneys are crucial organs for filtering blood and producing urine, but they are not the largest. Each kidney is relatively small and the combined surface area of both kidneys does not exceed that of the skin.

C) skin.

The skin is indeed the largest organ, covering an average surface area of about 1.5 to 2 square meters in adults. It plays essential roles in protection, sensation, and regulation of body temperature.

D) intestine.

The intestines are important for digestion and nutrient absorption, but they do not surpass the skin in size. The total length of the intestines is extensive, but their surface area does not compare to that of the skin.

Conclusion

The skin is definitively the largest organ of the body, primarily due to its extensive surface area that covers and protects the body. Other options like the liver, kidneys, and intestines, while vital, do not match the size and protective function of the skin. Thus, option C is the only correct answer regarding the largest organ.
