Final answer:
The House of Representatives makes its own rules in accordance with Article I, Section 5, Clause 2 of the U.S. Constitution. The Senate makes its own separate rules.
Step-by-step explanation:
Which Institution Makes the Rules for the House of Representatives?
The institution responsible for making the rules that members of the House of Representatives must follow is the House itself. According to Article I, Section 5, Clause 2 of the United States Constitution, both the House and the Senate have the power to establish their own rules for conducting business. This encompasses rules for parliamentary procedure and for disciplining members, including censure and expulsion with a two-thirds vote. The Senate operates independently when it comes to creating its rules, distinct from the House's procedures. Thus, the correct answer to the question is A. the House itself.
