问题补充：

The boy has two lovely dogs.

A. who live next door

B. which lives next door

C. whom lives next door

D. that lives next door

答案：

A. who live next door

B. which lives next door

C. whom lives next door

(答案→)D. that lives next door

解析：这个……的男孩有两只可爱的小狗。结合语境可知本句中先行词the boy为下文定语从句的逻辑主语，指人，故引导词用who。本句中who指代单数名词the boy，故后面谓语动词用单数，选D。
