Final answer:
Option A
This is because 'blue' and 'brown' both start with the same consonant sound, which is 'b'. Simile and Personification, the other options, are not present in the sentence.
Step-by-step explanation:
The sentence 'Brad wore his blue and brown blazer.' showcases the figure of speech known as Alliteration. Alliteration is the repetition of the same consonant sound at the start of words close together in a sentence or a line of poetry.
In this sentence, both 'blue' and 'brown' start with the same consonant sound, which is 'b'. Hence we see alliteration in action. Note that Simile and Personification are not reflected in this sentence. Simile is a figure of speech that compares two things using 'like' or 'as'. Personification is giving human qualities to non-human things.
