When citing a source with more than three authors for the second time, or more than five authors at any time, only the last name of the first author should be used, followed by "et al." to indicate there are other authors. "Et al." is an abbreviation for the Latin phrase "et alii," which means "and others." Therefore, the best choice is C, et al.
