I voted Metallica because they have such a wide fanbase and are the only band out of those listed that can still sell out entire stadiums. After 30 years in the business, that's definitely what I would consider influence.
You're confusing marketing and popularity here with influence. Influence is the type of bands that other bands would've listened to when they got started, which makes both Black Sabbath and Iron Maiden for example easily two of the most influential.

I wouldn't say they're entirely unrelated though. Tbh if Sabbath wasn't on the list I'd say it's a tie between Purple and Metallica.
