Answer:
C. Alliteration
Explanation:
- Alliteration is the repetition of usually initial consonant sounds in two or more neighboring words or syllables (such as wild and woolly, threatening throngs)
So the alliteration in the sentence "As boys, Brecca and I had boasted." would be the constant repetition of the B sound.
B words: boys, Brecca, boasted.
