Answer:
E) In general, the higher the expected return, the higher the risk.
Step-by-step explanation:
In order to attract potential investors, investments that bear a higher risk must offer a higher expected return. This is known as the risk-return tradeoff principle. Abiding by that same logic, investments with lower associated risk tend to offer lower expected returns since they are a "safe bet".
Therefore, the answer is E) In general, the higher the expected return, the higher the risk.
