What describes a proven doe?

A proven doe is characterized by her ability to successfully raise a litter. This definition highlights her effectiveness as a breeding rabbit, demonstrating her reproductive capability and maternal skills. A proven doe is often valued in breeding programs for her track record of producing healthy offspring, which is essential for breeders when selecting rabbits for future generations.

The other options do not specifically address the breeding success of the doe. While a doe that has been shown in competitions may have achievements in the show ring, this does not indicate her experience or ability in raising young. A registered pedigree provides information about the lineage of the rabbit, but does not reflect her performance as a breeder. Lastly, age alone, such as being less than a year old, does not determine a doe's proven status, as she may not have had the opportunity to reproduce yet. These factors all contribute to why option B is the most accurate description of a proven doe.
