**Core Concept**
Erythroderma, also known as exfoliative dermatitis, is a condition characterized by widespread scaling, erythema, and peeling of the skin involving more than 90% of the body surface area. It can be caused by various factors, including adverse reactions to medications.

**Why the Correct Answer is Right**
Drugs can induce erythroderma through various mechanisms, including the formation of drug-dependent antibodies, which can bind to the drug-bound T cells, leading to their activation and proliferation. This results in the release of cytokines and the subsequent inflammation of the skin. Certain drugs, such as carbamazepine, phenytoin, and sulfonamides, are known to cause erythroderma due to their ability to trigger this immune response.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because while it may cause skin reactions, it is less commonly associated with erythroderma.
**Option B:** This option is incorrect because it is not typically known to cause erythroderma.
**Option C:** This option is incorrect because while it may cause skin reactions, it is not a common cause of erythroderma.

**Clinical Pearl / High-Yield Fact**
When diagnosing erythroderma, it is essential to consider the patient's medication history, as discontinuation of the offending drug can lead to significant improvement in symptoms.

**Correct Answer:** C.
