Which dressing is described as peanut-based?

The appropriate dressing that is peanut-based is indeed the one labeled as Peanut Dressing. This dressing typically features peanut butter or peanut oil as its primary ingredient, which provides a rich, nutty flavor. Peanut dressings are often used in various culinary applications, such as salads, bowls, or as a dipping sauce, and they are particularly popular in Asian cuisine. The distinct characteristics it offers, including creaminess and a hint of sweetness, make it a favorite for enhancing the taste of various dishes. In contrast, the other dressings listed focus on different flavor profiles and base ingredients, making them unsuitable for the description of being peanut-based.
