• A. It causes bacterial infections
• B. It is the leading cause of skin cancer
• C. It leads to the formation of warts
• D. It primarily affects the immune system

Answer: (C)

The key feature of human papillomavirus (HPV) infections is their ability to lead to the formation of warts. HPV is known to infect epithelial cells, which can result in the development of benign growths such as warts on various parts of the body, including the hands, feet, and genital area. These warts occur because the virus triggers abnormal growth of the skin cells.

While HPV infections are associated with certain types of cancer, including cervical cancer, the formation of warts remains one of the most recognizable and direct effects of the virus on the skin and mucous membranes. This distinction emphasizes the relationship between HPV and benign lesions, marking it as a primary characteristic of the infection.
