The correct answer is A . The constraint is explicit: the SOW only includes one Admin Essentials training, but the client has twenty Workspace Admins distributed across North America, China, and Australia. A tailored video series provides reusable, asynchronous enablement that can reach all admins across time zones without exceeding scope. This is a practical learning-design response: it preserves project boundaries while still giving the admin audience role-specific training materials. Option B is poor consulting practice because offloading the training to the client’s IT team does not ensure quality, consistency, or alignment with the Slack launch plan. Option C is not enablement; 24/7 support is reactive and does not prepare admins to perform their role. Option D may be reasonable if the client wants expanded live training, but it changes scope and therefore does not meet the phrase “within the scope of the project.” The best answer is to supplement the single live Admin Essentials session with scalable admin-focused video content.
