Answer:
C. alliteration
Explanation:
Alliteration is "the occurrence of the same letter or sound at the beginning of adjacent or closely connected words." Dull and dark both start with d and have a duh sound. Therefore, it's alliteration.
Example of alliteration:
"The Furry Fox jumped over the fence"
personification is "a literary device that assigns human qualities and attributes to objects or other non-human things." so it can't be that since the sentence is not describing a object.
It's not Onomatopoeia because it doesn't describe a sound.
