What is the structure of our national legislative branch?

what are the parts?
where does it meet?
when does it meet?

The national legislative branch was established by the article I of the Constitution, the legislative branch is made up of the house of representatives and the Senate which make up the US congress. The senate is composed of 100 senators, 2 for each state. The House of Representatives have 435 people. Congress meets in the U.S. capital building in Washington, D.C. The Constitution (Article I, Section 4) originally provided that "The Congress shall assemble at least once in every Year, and such Meeting shall be on the first Monday in December, unless they shall by law appoint a different day."

If you need any more help let me know :))

i beleive a. is the only possible answer

in february 1787, congress decided that a convention should be convened to revise the articles of confederation, the nation’s first constitution. in may, 55 delegates came to philadelphia, and the constitutional convention began. debates erupted over representation in congress, over slavery, and over the new executive branch. the debates continued through four hot and muggy months. but eventually the delegates reached compromises, and on september 17, they produced the u.s. constitution, replacing the articles with the governing document that has functioned effectively for more than 200 years.
