问题如下：
Enterprise risk management（ERM）is the process of managing all corporation risks within an integrated framework. Which of the following options is not one of the contents of ERM?
选项：
A.Risk assessment for every project should be centralized.
B.The planner of the project conducts a preliminary assessment of the project risks.
C.Regularly assess the performance of each business unit and measure the impact of each business unit on the total risk.
D.The firm will accept the project only when the project's return is larger than the contribution cost of the project to the firm's total risk.
解释：
A is correct.
考点：Effective ERM的特点
解析：ERM要求的是decentralizing risk management, 是为了保障每个项目的总风险都被项目经理在内部评估中完整的评估出来。集中评估不满足这个目的。
老师好，看了之前其他同学的提问和解答，能理解基础班讲义第259页提到了decentralized（下图1标黄）。但是在基础班讲义第249页同时也提到了传统的risk management, 才是把每一个风险分开单独看待，我理解即为decentralized（下图2标黄）；同时，在基础班讲义第250页，也提到了ERM是centralized risk management （下图3标黄）。能不能请老师再详细的讲一下ERM下，什么时候要用decentralized，什么时候用 centralized？
