The Product Owner is accountable for effective Product Backlog management. The 2020 Scrum Guide states that this includes creating and clearly communicating Product Backlog items .
So the accountable person is clearly the Product Owner .
Why D is the best answer:
Option D identifies the Product Owner , which is the key official answer. However, the wording about a “proxy” is not the exact Scrum Guide wording. The Scrum Guide says the Product Owner may delegate the responsibility to others , but the Product Owner remains accountable . So while the option is not perfectly phrased, it is still the best available answer because it correctly names the Product Owner as the accountable person.
Why A is incorrect:
Developers may help refine, clarify, and break down Product Backlog Items, but they are not the accountable role for clearly expressing them.
Why B is incorrect:
The Scrum Master is not accountable for clearly expressing Product Backlog Items. The Scrum Master helps the Scrum Team understand Scrum and supports effectiveness, but Product Backlog accountability belongs to the Product Owner.
Why C is incorrect:
This wrongly assigns accountability to the Scrum Master. That is not supported by the Scrum Guide.
Why E is incorrect:
Again, this incorrectly makes the Scrum Master accountable.
Important correction to the option wording:
The official Scrum wording is not “appoint a proxy.” The correct concept is:
The Product Owner may delegate the work , but remains accountable .
