20.   The argument that the dominant form of family structure today is not the nuclear family, but rather it is a family which is modified and extended, is based on a number of facts: the existence of three-generational families, the amount of vertical and horizontal communication between family subunits, and the extent to which family members offer assistance to one another.

(A) family, but rather it is a family which is modified and extended, is based on a number of facts: the existence of three-generational families

(B) family, but is instead a family that is modified and extended, is based on a number of facts: three-generational families exist

(C) family, which has been modified and extended, is based on a number of facts: the existence of three-generational families

(D) family but a modified extended family is based on a number of facts: the existence of three-generational families

(E) family, but also a modified and extended family, is based on a number of facts: three-generational families exist

本來想選d的,但看似有雙重動詞,之後才選a. 因為我見過 but rather 對的例子.所以才選,但.... 請解答,謝謝

这个题是不是出错了？

答案是d,定语从句省略了that
