Where are plantar warts typically found?

Plantar warts are typically found on the sole of the foot due to the specific conditions that promote their development. These warts are caused by the human papillomavirus (HPV), which thrives in warm and moist environments such as those found inside shoes and on the ground in communal areas like swimming pools and locker rooms. The pressure and weight placed on the soles of the feet can also enhance the formation of these warts, causing them to grow inward, often resulting in discomfort or pain when walking.

In contrast, other options like the palms of the hands, back of the neck, or inside of the mouth do not provide the same conducive environment for the growth of plantar warts, as they are specific to the feet. Thus, the correct answer highlights the typical location where these warts manifest due to the unique factors affecting that area.
