The answer is A
B should be:
Do you need help with the printer?
C should be:
In the fall, I am planning to take piano lessons.
D should be:
You have a friend in me.
This is a B) correctly placed participial phrase.
If it weren't, that would mean the sentence would go like this: The audience playing an electric guitar listened to the musician, and then <em>playing an electric guitar </em>would refer to the audience, and not the musician.
there's not a lot of information given, but my guess is:
Poets set tone, and evoke mood.
The tone is the poet's attitude towards their writing, while the mood is the atmosphere received by the reader.
