Answer:
D. Raja, the goalkeeper, kept the other team from making any points
Step-by-step explanation:
Commas, as well as dashes and parenthesis, are used to enclose extra information to a sentence or information that is not necessary to the meaning of a sentence, that is, that can be removed from it without changing its meaning, like nonrestrictive appositive phrases.
“The goalkeeper” is a nonrestrictive appositive phrase, and therefore it should be enclosed by punctuation like commas. Appositive phrases are phrases containing a noun or pronoun that rename or re-identify another noun that is placed right beside it, like “the goalkeeper” which renames and gives us more information about a noun placed next to it: “Raja.” Furthermore, this phrase is nonrestrictive because it is not necessary for identifying the noun or pronoun that precedes it.
