Select the solid.

D: stuffed rabbit
The air inside a basketball is a gas. A gas expands to fill a space. The air fills all the space inside the basketball. If air leaks out, it will expand into the space around the ball.
A stuffed rabbit is a solid. A solid has a size and shape of its own. When you hold a stuffed rabbit in your hands, the stuffed rabbit still has a size and shape of its own.
Water droplets are a liquid. A liquid takes the shape of any container it is in. If you collect water droplets in a bucket, they will take the shape of the bucket. But the water droplets will still take up the same amount of space.
Grape juice is a liquid. A liquid takes the shape of any container it is in. If you pour grape juice into a different container, the grape juice will take the shape of that container. But the grape juice will still take up the same amount of space.
