clear sentence
watching the crowd’s reactions tells a dj when to speed up the music, slow it down, or try something different.

Explanation:

A DJ's goal when playing a song is to engage the crowd. The key idea provided (watching crowd reactions to adjust music) aligns with checking if the crowd is enjoying the song, as enjoyment is a core reaction. Other options: dance moves are not the main focus, hearing music is basic (not what a DJ "looks for" in terms of engagement), and singing the song isn't a typical DJ focus (enjoyment/reaction is).

Answer:

B. that the crowd is enjoying the song
