In certain circumstances the Development Team can order the items in the Product Backlog?

I recently passed PSM-1. For the prepration purpose, I had purchased the assessment at http://scrumstar.com/,

Here is one question I encountered during the test:

Q. In certain circumstances the Development Team can order the items in the Product Backlog.
A. No
Yes

Well I answered the question as No, as scrum guide clearly metions under product owner's responsibilities that "Ordering the items in the Product Backlog to best achieve goals and missions"

But after finishing the test, below is the feedback given by scrumstar.com


--------------------------------------------------------------
"The Scrum Guide says:

Product Backlog management includes: Ordering the items in the Product Backlog to best achieve goals and missions. The Product Owner may do the above work, or have the Development Team do it. However, the Product Owner remains accountable.
Hint:

This is a trick question to help you remember that the Product Owner can delegate his or her responsibilities and that in real-world situations things can be adapted to suit the needs of the organization. Things are not always implemented strictly 'by the book'."

---------------------------------------------------------------

I am kind of confused with this answer as well as the explanation. Can product owner really delegate his/her responsibilities to development team? or scrum master? And if he/she really can, then does those responsibilities include the primary and critical responsibilities like ordering the product backlaong?

Please help me here.
