A Correct answer
Explanation

'Prevail upon' is the correct idiomatic phrase meaning to persuade or convince someone to do something. The speaker convinced him to join their union. 'For' would suggest purpose, 'among' requires multiple people, and 'with' would suggest accompaniment rather than persuasion.
