Which statement is true? Portfolio A dominates portfolio B if: Portfolio A has a higher return that portfolio B Portfolio A has a lower volatility than portfolio B Portfolio A has a higher Sharpe ratio than portfolio B Portfolio A has either a higher expected return and a volatility at least as low as B, or a lower volatility and an expected return at least as high as B

The answer is "The last choice"

Explanation:

While comparing 2 assets or portfolio management, the risk of each portfolio and the rates of return of each portfolio should be taken into consideration. Whether the same danger is in the two assets. One should be preferred with both the higher return and one from the lowest risk should be recommended unless the two have the same rate of return. Portfolio A consequently either has a higher return and an at least as low fluctuation as B, or even lower volatility as well as an anticipated return at least as strong as B.
