Answer:
C . Enforce the law
Step-by-step explanation:
By Article two, section two of the United States Constitution, the president’s main duty is to enforce and carry out the laws that have been written by the Congress. He needs to make sure everything is done as intended and faithfully to the proclamation. He can ignore enforcing the law in case it is unconstitutional.
