Hello!
Your most likely answer would be-
A. A song
------------
However,
if you had to write out the title, i would go with "A Seashells Song" , but idk, that's just me.
------------
Small explanation-
The title "A song" would work the best, due to the poem stating that the seashell sang a sweet song whenever the shell was close to their ear.
------------------
Anyways, Hopefully this helps 'ya out! °ω°
( Could 'ya mark as Branliest answer pls? .w. )
