Many house builders offer rent-to-buy programs that enable a family with insufficient savings for a conventional down payment to be able to move into new housing and to apply part of the rent to a purchase later.

(B)   programs that enable a family with insufficient savings for a conventional down payment to move into new housing and to apply

(C)  programs; that enables a family with insufficient savings for a conventional down payment to move into new housing, to apply

(D)  programs, which enables a family with insufficient savings for a conventional down payment to move into new housing, applying

(E)   programs, which enable a family with insufficient savings for a conventional down payment to be able to move into new housing, applying

(C)的解释说：Using a semicolon here causes that to refer too broadly to the entire previous clause rather than specifically to programs

分号后应该跟完整的一个句子吧，为啥这里把错误解释成为修饰的扩大化呢？

看得真仔细啊...个人感觉，把第二句的that看作前一整句的代词，并作为第二个句子的主语，形成两个主句，用分号隔开,,,
