The product owner during the sprint

I've been studying for the scrum master exam and have come across a topic about what the product owner does during the sprint.

Does the product owner give the development team feedback during the sprint of the development team progress?

I think the operative word here is "progress" and my instincts tell me that the product owner does not give feedback to the development team on their progress.

However, the sprint review is an event within the sprint and so therefore there would be an opportunity to provide feedback on progress (Against the definition of done) .

I'm a bit confused on what the assessment would be looking for as an answer here. I've seen a version of this asked for in a sample assessment and I was marked wrong in answering that the product owner does provide feedback.

If I was tested on this topic in the actual assessment do you think the answer would be in the context of either
1) its not the product owners role to give feedback on progress - they should be focused on optimising value and the development team are self managing.
or
2) yes they definitely provide feedback at the sprint review and determine what meets DOD.
