Prolonged high exposure levels to penta can result in which of the following?

Prolonged high exposure levels to penta, or pentachlorophenol, can indeed lead to acne-like skin conditions or other skin disorders. This chemical is a known irritant and can cause dermal reactions, particularly with extended contact. The skin manifestations may include rashes, irritation, and acneiform eruptions, which are indicative of the body's response to prolonged exposure to toxic substances.

In contrast, options such as complete immunity to skin disorders, enhanced liver function, or no noticeable health effects are not accurate representations of the potential impacts of prolonged exposure to penta. The body's inability to develop immunity to such irritants and the presence of documented adverse health effects underscore the importance of handling this compound with care and taking appropriate protective measures to minimize exposure risks.
