Verified Answer :

B is probably the answer lol

Answer: B, C and D.

Explanation: All the words in option A start with a different consonant sound, so no alliteration is present, but we have three "b" sounds in option B (boreal, bear, blubber), three "ch" sounds in option C (Chambers, ChukChi) and two "h" sounds in option D (His, whole).
