Answer:
Option C
Explanation:
The president is allowed to approve the bill which means allow the bill to go through the further process to become a law or veto the bill which is when he rejects the bill and sends it back to the beginning of the law-making process. Laws are only able to be created when the president approves of the bill, which means your answer is indeed option C or "Both approve or veto a bill." The beginning of the law-making process can rather begin with the house of representatives, or the senate.
Hope this helps.
