An Alexa Skill Builder is building an interactive storytelling skill where the user can choose their own path through the story. The Builder wants Amazon Alexa to narrate the story and use custom audio for the dialogue for each character, along with various sound effects.
How can these requirements be met?

A. Record custom audio for each segment of the story, then stream audio files stored on Amazon S3 using the AudioPlayer interface for each segment of the story.
B. Develop each response as text, and let Alexa speak each part differently using SSML markup for <amazon:effect> to alter the Alexa voice for each character.
C. Record custom audio for each character voice and the sound effects in the story, then include the custom audio using SSML markup in the response.
D. Record the entire story as custom audio and stream the audio stored on Amazon S3 using the AudioPlayer interface.
