really bad.
Mr. Yang: If they don't finish it at home, then I sometimes ask them to do it during the break

Mrs. Lin: Me, too. But they still don't care. They just do nothing but play with their phones

What do I 的do在句子中是助動詞的角色，B選項have to do是必須做，have to是必須的意思，為一般動詞的片語，所以疑問句中助動詞後面放一般動詞的結構是對的。
那A選項的must和D選項的should都為助動詞，一個句子內只會有一個助動詞，如果選AD文法結構就會不對，所以不能選。
以上，希望有幫助到你！
