Anhidrosis, which is the inability to sweat, can lead to severely dry and cracked skin. This condition occurs because sweat plays a crucial role in maintaining skin hydration. When the body cannot produce sweat, it lacks the moisture that is essential for keeping the skin supple and hydrated. Consequently, the skin can become dry, leading to cracking and potential irritation.

In contrast, the other options do not accurately reflect the typical outcomes of anhidrosis. Severely oily skin is more likely related to other conditions that increase sebum production, while visible rashes may occur due to various dermatological issues rather than a direct result of decreased sweating. Skin blistering is typically associated with inflammatory or allergic reactions, which are also not direct consequences of anhidrosis. Therefore, the relationship between anhidrosis and skin dryness effectively underscores why this is the most appropriate choice.
