To become a law, typically a bill must be approved by:

a. The House of Representatives, the Senate, and the President

b. The House of Representatives

c. The Senate

d. The Supreme Court

I chose Letter A, but someone how my teacher said it was incorrect. I was completely shocked. He said the Congress and President can approve all they want, but the Supreme Court has the final "say" before a bill becomes a law.
I researched online through many different sources and didn't find any information about this.

This has been answered before. A is correct. Your teacher needs to go back to school!!
