请指教这道语法题

unqualifying 和 unqualified有什么区别吗？请指教这道语法题，谢了！

The Three women, liberal activists who strongly support legislation in favor of civil rights and environmental protection, have consistently received labor’s unqualifying support.

A. have consistently received labor’s unqualifying support

B. are consistently receiving the unqualifying support of labor

C. have consistently received the unqualified support of labor

D. receive consistent and unqualified support by labor

E. are receiving consistent and unqualified support by labor

正确答案是A，可是这里one’s所有格没有问题吗？为什么C不对？unqualifying 和 unqualified有什么区别？另外，这里用现在完成时，是不是因为有consistently为标志？

vagrant

用one's 所有格没有问题，反而更简洁了

unqualified 意思非常明确， 是绝对的，十分的全然的全面的意思，而unqualifying 意义不明确。 但是由于c中of 而不是from ,而且unqualified 前有the, 所以也不好。后来想一下，可能是把unqualifying 的意思看成跟unqualified 差不多，又表示主动，就这么用了。 欢迎指教。
