Answer:
d.
pianos
Explanation:
Here we have the mention of tin pans and sandpaper.
Sling your knuckles on the bottoms of the happy
tin pans, let your trombones ooze, and go husha-
husha-hush with the slippery sand-paper.
And here tin cans are mentioned
racing car slipping away from a motorcycle cop, bang-bang!
you jazzmen, bang altogether drums, traps, banjoes, horns,
tin cans
Still, in this poem, Pianos are nowhere to be found
