Final answer:
Congressional districts are apportioned by the Constitution, function as voting districts within each state, and their lines are typically drawn by state legislatures.
Step-by-step explanation:
The statement that is true about congressional districts is:
They are apportioned by the Constitution. Congressional districts are the geographic areas that determine the representation of each state in the United States Congress. The Constitution mandates that the House of Representatives be apportioned among the states based on population, meaning that the number of congressional districts per state is determined by the Census Bureau.
These districts function as voting districts within each state. They divide each state into smaller areas for the purposes of electing representatives to the House of Representatives. Each district represents a specific group of constituents who vote for a candidate to represent their interests.
The lines of congressional districts are drawn by state legislatures in most cases. State legislatures have the responsibility of redistricting, which is the process of redrawing the boundaries of congressional districts in response to population changes. However, in some states, independent commissions or state courts may also be involved in redistricting.
