Which of the following is the GREATEST benefit of identifying appropriate risk owners?

While risk owners hold responsibility for managing risks, the "greatest benefit" is the establishment of accountability. Accountability implies being ultimately answerable for the proper management and treatment of a risk, including the results of decisions made, which drives effective risk governance and ensures risks are not overlooked or unaddressed. Responsibility can be delegated, but accountability remains.

Consulting stakeholders about risk treatment options is part of a collaborative risk management process, but it's not the primary benefit of identifying risk owners; rather, it's an activity involving them.

Informing risk owners of risk treatment options is a necessary communication step, but the fundamental benefit of assigning ownership is the empowerment and answerability that comes with it, i.e., accountability.

Responsibility for risk treatment decisions is certainly established, but "accountability" (A) goes a step further, implying ultimate answerability and liability for the effectiveness of those decisions, making it the "greatest benefit" in terms of governance and assurance. Responsibility can be operational, accountability is ultimate.
