Explanation
According to the Agile Practice Guide, one of the agile principles is to "maximize value". This means that the project team should deliver the highest value features or products to the customer as early and frequently as possible. The Agile Practice Guide also states that "prioritization is a key activity for agile teams and their stakeholders". The project team should use various techniques and criteria to prioritize the backlog items, such as value, urgency, dependencies, and feedback. The Agile Practice Guide also suggests that "business value is a common prioritization factor". The project team should collaborate with the product owner and other stakeholders to determine the business value of each backlog item, and rank them accordingly. Therefore, the best answer is D.
