Senior management's role in the RACI model when tasked with reviewing monthly status reports provided by risk owners is accountable, as it means that they have the ultimate authority and responsibility to approve or reject the risk management decisions and actions, and to oversee the risk management performance and outcomes. The other options are not the correct roles, as they imply different levels or types of involvement or participation in the risk management process, such as being informed, responsible, or consulted, respectively.Reference:= CRISC Review Manual, 7th Edition, page 101.
