Which disqualification is associated with health issues in the fur of a rabbit?

The correct choice indicates that all listed conditions—abscesses, fungus growth, and mange—are disqualifications related to health issues affecting a rabbit’s fur. Each of these conditions signifies a serious health problem that can impact the overall wellbeing of the rabbit and the quality of its fur.

Abscesses are localized infections that can occur anywhere on the rabbit's body, including areas beneath the fur. They may lead to noticeable swelling or discharge, significantly affecting the appearance and health of the fur.

Fungus growth, particularly conditions like ringworm, can cause patchy fur loss and skin lesions, which not only alter the rabbit's coat but also indicate underlying health complications that require attention.

Mange, caused by mites, leads to inflammation, itching, and can result in significant fur loss. It presents serious concerns for both the rabbit’s health and its condition, making it inappropriate for competition in show settings.

Recognizing that these three health-related issues are serious enough to disqualify a rabbit emphasizes the importance of maintaining a healthy coat and skin condition for show animals, thus supporting responsible animal husbandry practices.
