Which breed of rabbit has a 4 class classification associated with it?

The classification of rabbit breeds into four categories typically refers to their size and fur characteristics. Each breed may fall into one of these categories based on specific criteria. In the case of the Havana, Mini Rex, and American Sable, all three breeds indeed have a recognized classification system that divides them into four classes: junior, intermediate, senior, and fur type. This classification is essential for show purposes, ensuring a standardized evaluation of rabbits based on their respective age and quality of fur.

Recognizing that all these breeds have their distinct classification under the four-class system confirms their relevance in breeding and showing contexts. This system aids judges and participants in understanding the various categories within which each breed can compete, allowing for a more organized show environment. Thus, the correct answer encompasses all the mentioned breeds, as they all share this common classification trait.
