Which color rabbit breed is mentioned as having a color in its name?

The breed that is indicated by its name as having a color is Tan. The term "Tan" directly refers to a specific color pattern seen in certain rabbit breeds, which features a rich, reddish-brown coloration with darker markings. This breed is often recognized for its distinctive color, which is central to its identity.

In contrast, the other choices do not denote colors in the same way. Angora refers to a breed known primarily for its long, luxurious fur. Lop, often associated with breeds that have long, floppy ears, also does not refer to a specific color but rather to a characteristic of the rabbit’s appearance. Similarly, Chinchilla is actually a variety in rabbit breeds that may have a color named after the rodent of the same name, but it is not as simply recognizable as "Tan" in the context of directly depicting color through the breed’s name. Thus, Tan stands out as the correct answer, as it is explicitly associated with a color.
