单选题The cat is the only&

单选题 The cat is the only one of her pets ___ she will have ____ on her bed.A.that, sleepB.which, it sleepingC.that, sleptD.that, it sleep

A解析考查定语从句和固定结构。定语从句That she will have sleep on the bed修饰先行词the only one. that指代the only one在句中做have的宾语。Have sb do sth让某人做某事；句意：这只猫是她的宠物中唯一的一个她让它睡在她床上的。

我也是这个答案
