**Core Concept**
Cutaneous larva migrans (CLM) is a skin condition characterized by a serpentine, itchy rash caused by the penetration of skin by the larvae of certain nematodes, typically hookworms. This condition is often associated with exposure to contaminated soil or sand.

**Why the Correct Answer is Right**
The correct answer is caused by the larvae of Ancylostoma braziliense, a type of hookworm. The larvae penetrate the skin, causing an inflammatory reaction and the characteristic serpentine rash. This is due to the host's immune response to the presence of the larvae and their subsequent migration through the skin.

**Why Each Wrong Option is Incorrect**
**Option A:** Not relevant to cutaneous larva migrans.
**Option B:** Not a common cause of CLM.
**Option C:** Not a type of hookworm associated with CLM.

**Clinical Pearl / High-Yield Fact**
CLM is often misdiagnosed as eczema or dermatitis, but it can be diagnosed based on the presence of a serpentine rash and a history of exposure to contaminated soil or sand.

**Correct Answer: D. Ancylostoma braziliense.
