Answer:
C. Song-like
Step-by-step explanation:
Piano is a lyric poem written by DH Lawrence. Like in most of Lawrence's poetry, emotions are the most dominant in this poem. The feeling that is expressed here is nostalgia, a longing for the past. There is no narration here.
This poem is not written in a particular constant meter. In each stanza, the lines get longer as the stanza goes on, showing that the speaker is going deeper into his memories.
However, this poem feels like a song, which is why option C is the correct one. Here, Lawrence uses the rhyming pattern of a hymn or nursery rhyme to make the poem feel like a song, while alluding to the music in the first stanza and using punctuation to control the rhythm.
