OG 12-034 关于介词后面引导名词性从句的问题

Beyond the immediate cash flow crisis that the museum faces, its survival depends on if it can broaden its membership and leave its cramped quarters for a site where it can store and exhibit its more than 12,000 artifacts.





(A)       if it can broaden its membership and leave





(B)        whether it can broaden its membership and leave





(C)       whether or not it has the capability to broaden its membership and can leave





(D)       its ability for broadening its membership and leaving





(E)        the ability for it to broaden its membership and leave


对于wether较if正确的问题上OG的解释中有一句：an interrogative  clause correctly follows a preposition .
So,她的意思是说if 引导的不是an interrogative  clause 。
那么究竟if 不能在on后面是因为if不能引导名词性从句（if 可以引导么？）还是说它引导的不是an interrogative  clause ？

问问题不要只说你的疑问 一定要把你的做题过程好好陈述一遍 怎么想的 最后怎么选的 最后正确答案又是什么 然后再说你的疑问 不然没人会理你的
