问题补充：

--- does this book belong to? --- It be Li Lei’s. There’s his name on it.

A. Who; must

B. Whom; can’t

C. Whose; must

D. What; may

答案：

A. Who; must

B. Whom; can’t

(答案→)C. Whose; must

D. What; may

解析： 根据回答语中有个Li Lei’s表示的是所属关系，对此提问通常用whose，根据最后一句在书上有他的名字，故书属于LiLei的可能性应该是最大，故用must，故选C。
