What does the term "clean" signify in specific rabbit breeds?

The term "clean" refers to normal fur present in certain areas of the body in specific rabbit breeds. In the context of rabbit breeding and judging, "clean" often denotes that the fur appears normal and healthy in quality and coverage on those parts of the rabbit where it is typically expected. This can relate to various breed standards where specific areas of the rabbit's body should have fur that is well-groomed and has the appropriate texture and length according to breed specifications.

Understanding this term is especially important for breeders and judges who assess the quality and conformity of rabbits to acknowledged breed standards, as it reflects not just the aesthetic aspects but also the health and well-being of the animals. The other options pertain to characteristics that do not encapsulate the meaning of "clean" in the context of rabbit breeds, focusing on markings, color definition, and hair growth, which are distinct from the definition of fur quality in particular areas.
