A product owner is asked why the Product Backlog is ordered rather than grouped into priority bands such as high, medium and low. What is the strongest answer?

• ABands are acceptable as long as each band is small.
• BAn ordered list says what should be picked up next and only one item can occupy each position, which forces the trade-off into the open. A band of twenty high priority items leaves the real decision unmade and read differently by everyone.
• COrdering is required by the Scrum Guide for tooling reasons.
• DBands are better because they are easier for stakeholders to understand.
