These are the choices I found on the internet:

b. It established that no president could be elected more than four times.
c. It limited the length of time a president could serve to eight years.
d. It limited the length of time a president could serve to four years.
The answer would be letter A - It established that no president could be elected more than two times. Twenty-second (Amendment XXII) amendment limits presidents to two terms only in the office. This was passed on March 21, 1947 and ratified on February 27, 1951.
