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

1.OG的解释是：
C Insofar as this is grammatical, using a
semicolon here causes that to refer too
broadly to the entire previous clause rather
than specifically to programs; the two
infi nitives should be joined by the
conjunction and, not separated by a comma.
这是什么语法点，希望有大牛解释下
2.此处的applying 的错误点是不是因为他的逻辑主语可以是builder且逻辑含义说的通，因此有歧义而排除？

第一点你可以看一下曼哈顿的逗号，分号，冒号，破折号的详述。

第二点是comma+Ving的用法，这个点资料很多，就是做状语，表伴随或者目的，这里都不行。
