下面关于contentFrame()方法代码描述正确的是（）
A. hot_artist = Song.query.order_by(Song.hits.desc()).limit(10).all()return render_template('home/contentFrame.html',hot_artist=hot_artist,hot_song=hot_song
B. hot_song = Song.query.order_by(Song.hits.desc()).limit(10).all()return render_template('home/contentFrame.html',hot_artist=hot_artist,hot_song=hot_song)
C. hot_song = Song.query.order_by(Song.hits.desc()).limit(10).all()
D. hot_song = Song.query.order_by(Song.hits.desc()).limit(10).all()
