You have a frequently asked questions (FAQ) PDF file.

A FAQ PDF file contains structured Q & A content. The QnA Maker (now part of Azure Language Service) can automatically extract questions and answers from such a document and build a knowledge base for conversational bots. This allows users to interact naturally with the content via chat interfaces.

Other options:

B. Text Analytics → Extracts insights, not conversational content.

C. Computer Vision → Used for image analysis.

D. LUIS → Handles intent detection, not static question–answer responses.
