Which official chairs the proceedings of the u. s. house of representatives? a. sergeant-at-arms b. speaker of the house c. president pro tempore d. vice president of the united states

Option B, Speaker of the House, is the right answer.

Explanation:

The Constitution of the United States has provisions that each of the two "Houses may conclude the Rules of its Proceedings, accordingly each Congress of the United States, upon assembling, maintains its own administrative rules of procedure". According to this provision of the Constitution as interpreted by the Courts implies that a new Congress is not bound to follow the rules of procedure of the preceding Congress. Such proceedings in the House of Representatives are executed by the Speaker of the House.
