The correct selections are A and C because both activities directly support the purpose of an elaboration workshop in a Guidewire InsuranceSuite implementation. Elaboration workshops are intended to clarify business needs, validate solution direction, and prepare the team to discuss functionality in a concrete, business-focused way. To do that effectively, the team must arrive prepared with a clear understanding of the customer’s most important requirements and with realistic examples that can be demonstrated in the session.

A. Create demonstration data necessary to demo functionality is correct because workshop discussions are much more effective when participants can see examples of how the system supports real business scenarios. Demonstration data helps analysts and other project team members walk through workflows, show expected outcomes, and confirm whether Guidewire capabilities align with customer needs. This supports richer discussion and better requirement discovery.

C. Identify customer's key business requirements is also correct because the elaboration workshop depends on knowing what matters most to the customer before the session begins. The workshop is not meant to start from zero; it builds on previously gathered understanding so that the team can refine, validate, and expand on those requirements in a structured way.

B is not the best answer because deployment notes are generally more relevant to later technical planning, release, or implementation activities, not early workshop preparation. D is not correct because writing detailed acceptance criteria for every story card before the workshop is usually premature. Acceptance criteria are typically refined after workshop discussions help clarify scope, behavior, and expected outcomes.
