Final answer:
The best way to rewrite the sentence "'Sure,' Phoebe." is option B, which is "Sure," Phoebe told him as it provides clear attribution of dialogue.
Step-by-step explanation:
The student's question asks for the best way to rewrite the sentence '"Sure," Phoebe.' When rewriting direct speech in literature, it's essential to ensure the sentence is clear and complete. It should indicate who is speaking and may provide some context for the dialogue.
Taking this into account, the correct option to rewrite the sentence is: B. "Sure," Phoebe told him. This revision is structurally sound, clear, and appropriately attributes the dialogue to Phoebe, who is speaking to John. The other options, A, C, and D, are either structurally incomplete or do not properly attribute the dialogue.
