Answer:
D. "Who?" I asked. "Never mind," she said. "No, I want to know," I told her.
Step-by-step explanation:
Option D uses dialogue most effectively because it shows an interaction between two speakers, someone that emits a message and someone that answers that message. Option D shows the messages and the answer, and there is a clear interaction between the two speakers, which is something that we can not see in the other options where there is only a quotation of what someone said and no answer.
