C. 435

The number of members in the U.S. House of Representatives is C. 435.

To identify the number of members in the U.S' House of Representatives, you can start by understanding the structure of the U.S. Congress. The U.S. Congress is made up of two chambers: the House of Representatives and the Senate.

The House of Representatives is the lower chamber and is based on the population of each state. To find the number of members in the House of Representatives, you need to know the number of seats allocated to each state. This is determined by each state's population.

The total number of seats in the House of Representatives is set at 435 members. This number has remained constant since 1913, following the passage of the Apportionment Act.

Therefore, the correct answer to the question is option C. 435.
