How many terms is a president limited to according to Amendment 22?

Amendment 22 of the United States Constitution clearly establishes that no person can be elected to the office of the President more than twice. This means a president is limited to serving two terms in office. This amendment was ratified in 1951 primarily as a response to Franklin D. Roosevelt's four terms in office, reflecting the desire to prevent any future president from holding such prolonged power. Therefore, the correct answer highlights this limitation: a president can serve up to two terms.
