A、Spectators. B、Athletes. C、Fans. D、Cheerleaders. C文中提到拉拉队到底是一种娱乐，还是一种让人烦躁的干扰，体育爱好者的看法是不一致的(disagree on)，故C项正确。

The official Olympic cheerleaders are a lot different than what you would see on the sidelines at basketball or American-style football games. Cheerleader Paola Bosio says about 500 girls tried out to become Olympic cheerleaders. "At the end we chose 100 girls. We have six groups, three working in ice hockey, two at speed skating and one in the mountains. So this is the first time that there is cheerleading in the Olympic Games, and we thought it was a good way to entertain the audiences." After being selected for the team, [5]the new cheerleaders practiced for four and a half months. But during that time, all they learned how to do was to wave their orange and gold pompons, and jump up and down to whatever music might be playing at the stage. [6]Fans disagree on whether the cheerleaders are entertaining or just an annoying distraction. After all, they do not actually cheer and they do not wear sexy uniforms. [7]The all-girl team, which ranges in age from 15 to 26, is dressed in bright orange and gold uniforms that cover them almost from shoulder to toe.
