Final answer:
To determine what the bold appositive phrase refers to, identify the noun immediately before the phrase in the sentence. The appositive provides additional information about that noun.
Step-by-step explanation:
To answer the question about what the bold appositive phrase refers to, we would need the specific sentence that contains the appositive phrase. An appositive phrase is a group of words that restates or explains more about a noun that comes just before it. For example, if we have the sentence 'Moe Szyslak, a star basketball player, won the game for his team,' the bold appositive phrase 'a star basketball player' provides additional information about 'Moe Szyslak.'
In the above example, the bold appositive phrase refers to option B, 'Moe Szyslak.' It is important to identify the noun that precedes the appositive to determine what it refers to. Typically, the noun immediately before the appositive is the one being explained or redefined by the appositive.
