Answer:
The sentence that is punctuated correctly is:
B. Arguably, Camilla plays the best defense on our soccer team.
Explanation:
We need to add a comma after the adverb "arguably" because it is modifying the entire sentence. This is common when adverbs come at the beginning of a sentence.
We should not add a comma anywhere else in this sentence. The other elements have no reason to be separated by a comma. The sentence contains no appositives. For that reason, the correctly punctuated sentence is:
B. Arguably, Camilla plays the best defense on our soccer team.
