a quick question from prep 1-69

The proliferation of so-called
cybersquatters, people who register the Internet domain names of

high-profile companies in hopes of
reselling the rights to those names for a profit, led to passing the

Anti-Cybersquatting Consumer
Protection Act in 1999, allowing companies to seek up to $100,000

in damages against those who register
domain names with the sole intent of selling them later.

(A) passing the Anti-Cybersquatting
Consumer Protection Act in 1999, allowing companies to seek

up to $100,000 in damages against
those who register domain names with the sole intent of selling

(B) the passage of the
Anti-Cybersquatting Consumer Protection Act in 1999, which allows

companies to seek up to $100,000 in
damages against those who register domain names with the

sole intent that they will sell

(C) the passage in 1999 of the
Anti-Cybersquatting Consumer Protection Act, which allows

companies to seek up to $100,000 in
damages against those who register domain names with the

sole intent of selling

(D) the Anti-Cybersquatting Consumer
Protection Act, which was passed in 1999, and it allows

companies to seek up to $100,000 in
damages against those who register domain names with the

sole intent to sell

(E) the Anti-Cybersquatting Consumer
Protection Act, passed in 1999 and allowing companies to

seek up to $100,000 in damages
against those who register domain names with the sole intent of

selling

the answer should be C and I am wondering whether D, besides the Anti-Cybersquatting Consumer
Protection Act should be the passage of~, whether it allows here, it could be dropped?

GMAT的原则是尽量简洁.可以直接用一个动词或者名词表达的，就不用定语从句来修饰。
而且D把一个表示结果的分句用一个独立句子来表示，改变了原句的中心也错。
这里用with the intent of doing sth比with the intent to do更适合表达这个intent的内容。
