Consider the following​ two, completely​ separate, economies. The expected return and volatility of all stocks in both economies is the same. In the first​ economy, all stocks move togetherlong dash in good times all prices go up together and in bad times they all fall together. In the second​ economy, stock returns are independentlong dash one stock increasing in price has no effect on the prices of other stocks. Assuming you are​ risk-averse and you could choose one of the two economies in which to​ invest, which one would you​ choose? Explain. ​(Select the best choice​below.)
A. A​ risk-averse investor would choose the economy in which stock returns are independent because risk can be diversified away in a large portfolio.
B. A​ risk-averse investor is indifferent in both cases because he or she faces unpredictable risk.
C. A​ risk-averse investor would prefer the economy in which stock returns are independent because by combining the stocks into a portfolio he or she can get a higher expected return than in the economy in which all stocks move together.
D. A​ risk-averse investor would choose the economy in which stocks move together because the uncertainty is much more​predictable, and you have to predict only one thing.
