Answer and Explanation:
The poem "sympathy" uses the ABAABCC rhyme scheme from the beginning to the end. This promotes stability in the sound that the lines promote, presenting a more harmy and stable musicality.
The alliteration highlights the words "beats" and "bars". This means that alliteration is a figure of speech that causes the repetition of consonant phonemes in the same sentence or paragraph, in the case of this poem, along the same line. This also promotes sound stability to the poem.

I think it would be d or a
Increasing would be the answer.
