Which of the following is an example of a patch?

Explanation:
A patch is a flat, non-palpable color change in the skin that is at least 1 cm in diameter. Cafe-au-lait spots fit this definition because they are flat, uniformly pigmented areas that are typically larger than 1 cm and present from birth or early childhood. Freckles are small pigmented spots usually under 1 cm, classified as macules. A nevus (mole) is typically raised, though some flat types exist, but the common teaching emphasizes a raised lesion. A blister is a raised, fluid-filled lesion, not a color change. So cafe-au-lait is the example that matches a patch.
