The correct answer is "C".
A proposal for legislation or "bill" may originate not only both the House of Representatives (including its committees) or the Senate, but it may also come from the executive. This bill is handed to the appropriate committee in the House of Representatives for its further debate. It then has to be approved by a majority of votes in both the House of Representatives and Senate. Finally, after approval by both houses, it has to be approved by the President in order to become a Law.
