(A) that is, that screens out a percentage of minorities or women disproportionate to

(B) which means, that screens out a percentage of minorities or women disproportionate with

(C) which means, that screen out a percentage of minorities or women disproportionate with

(D) that is, that screen out a percentage of minorities or women disproportionate to（D）

(E) that is, that screens out a percentage of minorities or women disproportionate with

同意选D，that is是插入语，是2个从句并列修饰mechanisms，但是问题似乎应该有and连接２个定从吧？除非理解成that is这个插入语当成连词成分了？是这样理解吗？
