Since it is not possible to update owner of a record to a user who does not have Read access at the object level, B and C are incorrect.
A, while being the most correct option, is also incorrect since the ownership of the driver's manager would stay the same if the driver changes manager, requiring a more complex solution to update the ownership in that case. For example, an after update trigger or record-triggered flow on the User object to update the ownership of the related Performance Feedback records when the manager changes

"You can give ownership of a record to another user as long as that user has at least Read permission for the type of record being transferred."
so you are all wrong

i think that C is the best answer and i' totaly agree with @sanjana because using roles hierarchies wil give managers more acces in the current role hierarchy implementation not all the (Assuming managers we don't know how they are organized ) they are more then one ;)

Even i feel B is the correct answer. As the drivers manager changes automatically the role hierarchy will take care of the Access to the new manager

Because it says "accessible to people above them in the Role Hierarchy, even when the driver changes managers", the answer will be C

B should be correct.

Removing Read permission on the Driver profile will prevent the driver from seeing any feedback records, regardless of ownership.
After feedback record is submitted that Driver become owner of feedback (and cannot see the record due to above).
Now anyone above Driver Role (that is manager) can see the record.

Role hierarchy usage is better oprtion than creating ownership base rule.

B is the correct answer
