I thought A is the correct answer because it sounds if most viewers started to watch the 1st episode of the program because of the network's ad, it sounds the ad had huge influence or better influence. After all "most" means more than 50%. (Nothing can be more influential than this because it's more than 50%) Why is A wrong? :(
