Which statement best describes a doe?

A doe is specifically defined as an unaltered female rabbit. This terminology highlights the sexual status of the rabbit, distinguishing it from other categories such as neutered animals or those that have not yet produced offspring. While a doe can indeed give birth, the term itself does not imply that she has done so; rather, it focuses on her being female and intact, meaning she has not undergone surgical alteration.

Other options introduce specific conditions that do not universally apply to all does. For example, while option A describes a neutered female, that would not be correct in identifying a doe, as it emphasizes an altered state. Option C suggests a female that has given birth, limiting the definition and making it less inclusive. Lastly, option D inaccurately describes a young rabbit, regardless of gender, which does not relate to the reproductive status or life stage relevant to defining a doe. Thus, the best descriptor of a doe is indeed as an unaltered female rabbit.
