An Alexa Skill Builder is creating a skill that will identify an actor who spoke a famous piece of movie dialog, given just the dialog text and an optional movie name. The Builder created the FindActorIntent as shown below, but Amazon Alexa returns an error when it builds the model.

Why is Alexa failing to build the model?

A. Intents can have one built-in slot type only
B. All sample utterances within an intent should have both slots
C. SearchQuery is combined with another intent slot in an utterance.
D. “Dialog” is a reserved keyword in the Alexa Interaction Model schema.
