Answer 1

Step-by-step explanation:

The answer is A

Answer 2

A. Congress may override a president's veto.
The idea behind checks and balances is to spread the power evenly between each government branch, (Separation of powers). While the president can veto a Congressional bill thus exercising a separation of power he may be paradoxically overrided if 2/3 of both the House and the Senate vote in favour of doing so.
