Answer:
d. apportionment of legislative seats
Step-by-step explanation:
The case Baker v. Carr was a landmark case of the Supreme Court in which the Court argued that redistricting was a topic that the federal courts were allowed to examine. This was a response to the fact that the state of Tennessee has argued that redistricting was a political, and not a legal question. Redistricting is an important process in the United States as it determines the apportionment of legislative seats in Congress.
