Correct answer is C

A. Background ❌
This section provides context about the project, like business challenges or the reason for initiating the project — not where training responsibilities are documented.

B. Terms and Conditions ❌
This outlines legal or contractual items like payment terms, liability, intellectual property, etc. — not the specific work to be done.

C. Scope ✅
This is where you'd define who is responsible for training, which users will be trained, and what methods will be used (e.g., in-person sessions, video tutorials, documentation). It ensures clear understanding between the client and the consultant on deliverables.
