Using the Project Scenario and the additional information provided for this question in the Scenario...

In the context of Agile Project Management when developing the Solution Architecture Definition (SAD), the two statements that are appropriate are:

A. Paper-based drawings are to be used for each option being considered for the building and gardens.

C. The Architecture Angels' Marketing Director can request a SAD to illustrate the achievability of complex elements of the solution.

Here's the rationale:

•A: Agile methodologies support the use of simple and understandable tools that can quickly convey ideas and be easily changed. Paper-based drawings align with this by providing a flexible and adaptable way to represent different options, which can be rapidly modified in response to feedback.

•C: It is important for the Marketing Director, who understands the market and customer needs, to request clarification on complex elements to ensure that the proposed solutions are feasible and aligned with customer expectations. This contributes to creating a solution that is viable both technically and from a business perspective.
