Answer:
C) Invest $2500 in a risk free asset and $2500 in a stock with beta of 2.0
Explanation:
Stock that is beta 2 means that it is twice as volatile as the whole market. Meaning for example if the market is expected to move by 5% this stock will move 10%. New startup firms that are fast-growing usually have stocks in this category. It is more risky thank normal shares but no too much. We can invest $2,500 here.
We invest the remaining $2,500 in risk-free assets
 This is a backup on the chance that the investment on beta 2 stocks do not perform, the risk-free assets will make up for losses.
 
        
             
        
        
        
Common stockholders will not receive any money before the preferred stock holders in the case of the company having to liquidate.  So thats a disadvantage.  Preferred stockholders tend to get higher dividends paid out to them, which is an advantage.
