What physical feature is described as the 'rump' of the rabbit?

The 'rump' of the rabbit refers to the hind portion of its back, which is a crucial part of its anatomy. This area is significant both in terms of the rabbit's posture and movement. The rump comprises muscles that support jumping and quick movements, which are essential for a rabbit's survival in the wild. It also plays a role in the overall body balance and posture of the rabbit. Understanding this anatomical term is important in rabbit care and management as it helps in recognizing health issues or body condition during assessments. The other options do not pertain to the description of the 'rump' and instead refer to completely different parts of the rabbit's body that do not provide the same functional or anatomical context.
