What does ARBA stand for?

The correct choice, B, stands for the American Rabbit Breeders Association, Inc. This organization is significant in the rabbit breeding community as it sets standards for rabbit breeds, promotes rabbit shows, and provides resources and support to breeders. Established in the early 20th century, the ARBA plays a crucial role in ensuring proper practices in breeding and exhibiting rabbits, thereby fostering a community of responsible rabbit owners.

The other options, while they may sound plausible, do not accurately represent the established national organization dedicated to rabbit breeding and shows in the United States. Each of those associations mentioned would either refer to non-existent organizations or focus on different aspects of animal breeding, none of which have the same recognized role in the rabbit community as the American Rabbit Breeders Association, Inc.
