关于英语代词的问题,
--Mike,have you ever heard of the latest water heater using solar energy?---Yes,of course,but I haven’t decided whether to buy_________.A.it B.one C.this D.that
答案应该选B,但是为什么不能选A或C,A,C,D都是表示特指的代词用法有什么区别啊?

A.特指某样具体事物
B.指代一个热水器
C.这样事物
D.那样事物
这题主要是指我不确定要不要买一个（前文提过的）热水器,前文提的时候热水器是一类的太阳能热水器,指的是一类事物,所以后文要用one.
如果是在商场指着一台热水器说要不要买,那么后文用it或this都是可以的····
