Answer:
D). The alliteration between "shadow" and "ship".
Step-by-step explanation:
Alliteration is demonstrated as the literary device that involves the repeated or continuous occurrence of identical consonant sounds in at least two or more adjoining or nearby words in a line. Such a device is primarily employed to grab the readers' attention towards a particular element and develop a rhythm and melody to the text.
In the given passage, the use of 'alliteration between the words 'shadow' and 'ship'(repeated use of consonant 's') connotes to recall the image of the Mariner observing the water snakes in the poem 'The Rime of the Ancient Mariner' authored by Coleridge. Therefore, option D is the correct answer as the other options do not employ alliteration as they do not involve the repetition of similar consonant sounds.
