A. should have been given
B. ought to be given
C. would have been given
D. must be given

(答案→)A. should have been givenB. ought to be givenC. would have been givenD. must be given解析：考查情态动词。句意：问题：该问题对他来说不难，对吗？回答：不难。他应该被给予一个更难的问题。该对话整个谈论的是发生在过去的事，与现在无关，故答案应在选项A或C中选。should have done表示“该做而未做的事”，合题意，是正确答案。
