What does BIS signify in rabbit shows?

BIS stands for Best in Show, a title awarded to the rabbit that is deemed to be the best overall among all the entries at a rabbit show. This recognition is typically based on various criteria, including breed characteristics, overall health and condition, and how well the rabbit conforms to the breed standards. Winning Best in Show signifies that this rabbit stands out above all others in the competition, showcasing excellence in quality and presentation.

The other options propose alternative meanings that do not correspond to recognized titles in rabbit showing. Best in Strain, Best in Size, and Best in Style do not exist as formal designations within the context of rabbit competition standards, making them less relevant to the terminology used in these events. Thus, Best in Show is clearly the term that accurately encompasses the highest accolade awarded at rabbit shows.
