Final answer:
The Speaker of the House sends a bill to one of the House's standing committees once it has been introduced. This is the initial step in the legislative process before the bill can eventually be sent to the President after House and Senate approval.
Step-by-step explanation:
Once a bill is introduced in the U.S. House of Representatives, it is initially placed in the hopper, given a number starting with H.R., and read to the members. The Speaker of the House is responsible for sending the bill to one of the house's standing committees. The correct answer to the question of where does the Speaker of the House send a bill once it has been introduced is C) Committee.
The legislative process includes various stages, such as committee hearings, markups, and floor debates. Only after a bill has been approved by both the House and the Senate, and reconciled if necessary, does it go to the President for signature or veto. Importantly, all bills for raising revenue must originate in the House, while the Senate may propose amendments.
