英语单项题--How much should I pay____two rooms?
--How much should I pay____two rooms?
--What day? A room ____ weekdays is seventy dollars, but eighty dollars _____ weekends.
A. for; for; / B. for; of; / C. off; for ; for D. / ; on ; on
书上答案是B
觉得此题有问题,请问各位有何高见?

--How much should I pay for two rooms? 我应该为两个房间支付多少钱?
--What day? A room on weekdays is seventy dollars, but eighty dollars on weekends. 什么日子?一个房间平时是七十美元,但在周末是八十美元。
for:为——
on+日期:在哪一天

应该是D

我也觉得
for on on
pay for 是固定短语
on weekdays 指在工作日
on weekends 指在周末

答案应该是for on on
