The idiom "face the music'' is often used when someone must accept punishment or criticism for what they did.
In the sentence, the person made a mistake at work — so now she has to accept whatever results from that mistake.
Let’s look at the options:
- Option A: Listening to music is not related to the meaning.
- Option B: Facing consequences fits perfectly.
- Option C: Performing is unrelated.
- Option D: Conflict resolution doesn’t match the sentence.
Hence, the best meaning is Option B.
