The correct response is: to accommodate changes in state populations after the census is taken.

Congressional seats are reapportioned every decade to ensure that each state is represented fairly based on their population changes. After each census, the population data is used to determine how many seats in the House of Representatives each state should receive. This process is required by the U.S. Constitution to ensure equal representation for all citizens.
