Step-by-step explanation:
The total number of full-fledged members of Congress is 435 (option b). The United States Congress is a bicameral institution consisting of the House of Representatives and the Senate. The House of Representatives has 435 members, while the Senate has 100 members. The number of representatives in the House is determined through a process called apportionment, which is based on U.S. Census Bureau population data. The number of representatives has been fixed at 435 since the Permanent Apportionment Act of 1929.
