(A) that funding for the park's development, which could be open to the public early next year, is

(B) that funding for development of the park,
            which could be open to the public early next year, be

(C) funding for the development of the park,
            perhaps open to the public early next year, to be

(D) funds for the park's development, perhaps open
            to the public early next year, be

(E) development funding for the park, which could
            be open to the public early next year, is to be

Choice B is best. Choice A attaches the relative clause which could be open ... to the noun development, when, in fact, it is the park that could be open. Choice C omits that, the object of proposed that is needed to introduce the clause describing the proposal. C also uses to be unidiomatically where be is correct: the commission proposed [that] funding ... to be obtained is wrong.

Choice D incorrectly uses perhaps open to modify development；the phrase should be modify park.

这里可见，D项错误是在与perhaps open to 的modify对象错了，而不是perhaps open to 在语法上有任何问题。

perhaps open to应该不是一个非限制性定语从句（我记得语法书上说非限制性定语从句不能省略代词），它到底是什么修饰成分呢？？请NN回答这个弱弱的问题。
