The answer was B...Ion Man
Though Ion Girl later joins the Super Squad Auxiliary in book 3: League of Evil. This is after Ion Man becomes Ion Girl and is recruited to join a sort of Suicide Squad to save the world.
Cindy was first so she gets 5 points and Chris Dilloway was second so he gets 3 points, making the score:
Cindy 10, Chris 3, and Everyone Else 0 but obviously the game is young.
