Which of these is not a football (soccer) position?

This question has so many things wrong with it, it's comical. For starters it's mixing volleyball and soccer.

little b, The setter is in volleyball, not football.

Giggle, There is nothing wrong with the question. Although the definition is incomprehensible to people who don't have specialist knowledge about the subjects. They quite often give information about all the optional answers, so it's not " mixing" anything.

I've not heard of the setter in football
