Who is the best "Risk Owner": A - Risk Manager B - Project Manager C - Project Team Member D - Any Stakeholder?

The best Risk Owner is Project team member

I think the best risk owner is the Risk Manager.

c    project team member  is the best risk owner

My personal answer to experience is all of the above

A risk owner is an individual, generally a project team member, who is responsible for the management, monitoring, and control of an identified risk, including the implementation of the selected responses.
