In which sentence should a comma be deleted?

Adam Smithfield is a sullen, morose, boy.

Sarah was, however, happy to hear the news.

Sheila, Elden, and Steven attend public school.

It is up to you, Austin, to earn your own money.

The correct option in this case is A.

Explanation:

The second comma after the morose is unnecessary. As it is not splitting the text or differentiating between two nouns. It is separating the adjective from the noun which is not a correct application of the comma so the corrected sentence would be  Adam Smithfield is a sullen, morose boy.
