Final answer:
Option B, 'So little they rose, so little they fell,' is an example of alliteration from the poem "Inchcape Rock" with the repetition of the 'l' sound.
Step-by-step explanation:
The example of alliteration in the given options from the poem "Inchcape Rock" is B. So little they rose, so little they fell. Alliteration is the repetition of consonant sounds at the beginning of words in close proximity. In this case, the letter 'l' is repeated at the beginning of 'little,' 'they,' 'little,' and 'fell.' Alliteration often adds rhythm, emphasis, or aesthetic quality to poetry or prose. The other options provided do not demonstrate the same clear use of alliteration.
