The answer you are looking for is D
It would be "Article I" of the Constitution that establishes the legislative branch of the government, due mostly to the fact that the Founding Fathers wanted to place the greatest emphasis on this branch.
Here is my new and revised answer from my own words.
The importance of the Marbury vs. Madision Case is that the Supreme Court applied the new concept of judicial review. In this court case, this was a crucial event because it would be the first time that it was properly used. Therefore, this allowed the government to easily distinguish if laws were considered constitutional or unconstitutional and overall set a strong foundation for the judicial branch of government in the near future.
I hope this answer helped with your question, and hope you have a lovely day!
