The complex nature of derivatives has led to:
选项：
A.reliable financial models of derivatives markets.
B.widespread trust in applying scientific principles to derivatives.
C. financial industry employment of mathematicians and physicists.
解释：
C is correct. Many derivatives are extremely complex and require a high- level understanding of mathematics. As a result, the financial industry employs many mathematicians, physicists, and computer scientists. A is incorrect because scientists create models of markets by using scientific principles that often fail. For example, to a physicist modeling the movements of celestial bodies, the science is reliable and the physicist is unlikely to misapply the science. The same science applied to financial markets is far less reliable. Financial markets are driven by the actions of people who are not as consistent as the movements of celestial bodies. B is incorrect because the complex nature of derivatives has made many distrust, as opposed to trust, derivatives, the people who work with them, and the scientific methods they use.
