A sentence could be “The seas churned”
I'd go with B - Article. There are hundreds of good examples for the answer being B. For example, "a book" ('a' is an article - 'book' is a noun), "an apple" ('an' article - 'book' noun). Those are just the simple ones.
Simile because it has “like” in it.
Hello.
The preposition in the sentence is under. A preposition is a word meaning where the noun is in the sentence, the noun is tree, the preposition is under.
