问题如下：
Phoenix is proficient in risk management. He has recently taught the concepts of ERM to major companies. Which of the following options describes the core concepts of ERM?
选项：
A.To maximize firm's value by minimizing the expected risk of the firm.
B.To maximize firm's value by eliminating the total risk of the firm.
C.To maximize firm's value by optimizing the total risk of the firm.
D.To maximize firm's value by minimizing the unexpected loss of the firm.
解释：
C is correct
考点：ERM
解析：ERM的目标并不是一味地将公司的风险降低至最小，而应该是合理化、最优化公司的风险，来最大化公司价值。除C以外都是干扰项。
不应该选D么？讲义249页，第一段，minimizing unexpected earnings volatility and maximizing enterprising value.这不是在最大化企业价值的同时，最小化风险么？
