The correct answer is c. 60 days. The length of time that a president can commit American forces to combat without the approval of Congress is generally limited to 60 days under the War Powers Resolution of 1973.

To find the answer to this question, you could start by searching for information about the War Powers Resolution. This law was passed by Congress to define the powers of the president and Congress in committing U.S. forces to combat abroad. You can search for phrases such as "War Powers Resolution," "president's power to commit forces to combat," or "presidential power without congressional approval."

Through your search, you would find that under the War Powers Resolution, the president can only commit forces to combat without a congressional declaration of war for up to 60 days. If the conflict surpasses the 60-day limit, the president must obtain congressional authorization to continue military operations. So the correct answer would be c. 60 days.
