The statement that best describes the "checks and balances" plan is:
"Lets Congress and the president challenge each other's actions."
The system of checks and balances in the U.S. government is designed to prevent any one branch (Congress, the President, or the Judiciary) from gaining too much power and allows each branch to challenge or check the actions of the others. It doesn't give any single branch the final power to end a bill; instead, it requires cooperation and oversight among the branches.
