The correct answer is D. Asylum.
A rabbit is an animal that lives in a burrow. A lunatic is a person who is mentally ill. An asylum is a place where mentally ill people are kept.
A burrow is a hole in the ground that a rabbit lives in. It is usually made of dirt and grass, and it has a small opening at the top. Rabbits use their burrows to sleep, hide from predators, and raise their young.
An asylum is a place where mentally ill people are kept. It is usually a large building with many rooms, and it has staff who are trained to care for the patients. Asylums were once called "insane asylums" or "mental institutions."
The other options are not correct because they are not places where lunatics live. A prison is a place where criminals are kept. A cell is a small room in a prison. A barrack is a building where soldiers live.
