Answer 1

Answer:

B. on

When you congratulate someone on something you give them your good wishes because something special or pleasant has happened to them, e.g. "I'd like to congratulate you on your marriage". When you congratulate someone for something you praise them for an achievement, e.g. "I'd like to congratulate the staff for their good job".
