The correct answer to this open question is the following.
Although there are no options attached we can say the following.
Equality of opportunity is a central value in the American political system. I am going to choose the United States Congress
I consider that US Congress is most responsible for advancing the principle of equality of opportunity in the United States because Congress has the power to create laws and legislation that aims to strengthen the principle of equality.
Let's have in mind that the American founding fathers created the nation based on liberty and equality, and those concepts were an important part of the Declaration of Independence promulgated on July 4, 1776, and of the Constitution created during the Constitutional Convention of Philadelphia in 1787.
American legislators should be committed to creating the kinds of laws that support the principle of equality, instead of spending too much time with lobbyists, negotiating legislation that benefits particular interests or political groups' interests.
US citizens voted for congressmen to represent them and fight for their concerns and demands.
The answer is c.
Hope I helped!
