There is growing demand in the state for “initiative and referendum,” a procedure that allows voters to propose and pass laws, as well as to repeal them.

(A) allows voters to propose and pass laws, as well as to repeal them

(B) allows voters to propose, pass, and to repeal laws

(C) allows voters to propose, to pass, and repeal laws

(D) will allow the voter to propose, pass, as well as to repeal laws（A）

(E) will allow laws to be proposed, passed, as well as repealed by voters

两个问题1.a中"to propose and pass laws,as well as to repeal them"符合to do and do ,and do的规则么,有没有破坏平行结构?

2.这里的them 会不会造成指代上的模糊,有可能也指代前面的voters.顺便问一下形如 a do b (a ,b 单复数同),most of them(it)(作b的同位语)....这种情形下,指示代词them 和it 的使用有问题么,如果同时有most of wich的选项,哪个更好些?

迷惑中,请路过的高人帮忙作答......
