Congress passes a bill- The president veto's a bill- congress overrides the presidential veto

What judicial bench is involved in this? No, it's not A.

If the bill pass after president veto it, is the vote of congreese called supermajority?

No, the principle of U.S. government illustrated in the sequence above is checks and balances.

Checks and balances is a principle in the U.S. government that ensures power is distributed among different branches and levels of government, preventing any one branch or level from becoming too powerful. This system enables each branch to check the actions of the others and maintain a system of accountability.

In the given sequence, Congress passes a bill, which represents the legislative branch exercising its power. Then, the president vetoing the bill represents the executive branch using its power to reject legislation. Finally, Congress overriding the presidential veto demonstrates the legislative branch's ability to check and balance the executive branch by reversing the president's decision and making the bill into law despite the veto.

Therefore, the correct answer is checks and balances.
