问题如下：
Kelly Amadon, CFA, an investment adviser, has two clients: Ryan Randolf, 65 years old, and Keiko Kitagawa, 45 years old. Both clients earn the same amount in salary. Randolf, however, has a large amount of assets, whereas Kitagawa has few assets outside her investment portfolio. Randolf is single and willing to invest a portion of his assets very aggressively; Kitagawa wants to achieve a steady rate of return with low volatility so she can pay for her child's current college expenses. Amadon recommends investing 20% of both clients' portfolios in the stock of very low-yielding smallcap companies. Amadon least likely violated the CFA Institute Standards of Professional Conduct in regard to his investment recommendations for:选项：
A.only Randolf's portfolio.
B.only Kitagawa's portfolio.
C.both clients' portfolios.
解释：
In Randolf's case, the investment may be appropriate given this client's financial circumstances and aggressive investment position. This investment would not be suitable for Kitagawa because of her need for a steady rate of return and her low-risk profile.不理解为什么不选C？对于R同学，他是个激进投资者，投股票的话风险高收益也高好理解，但小盘股是low yield的话，因为收益低所以对R同学不适合对么？另外对对于K同学，他不是希望有个稳定的收益么？股票收益应该不稳定吧，为什么对他来说就是合适的？
