Answer:
I, II, and III are all correct and part of this model
Explanation:
The CAPM model or Capital Asset Pricing Model indicates the relationship between the amount of risk and the expected profit for a certain investment. This model holds many assumptions, which from the ones provided we can say that assumptions I, II, and III are all correct and part of this model. The only assumption that is not correct is IV, since the level of risk aversion that each investor has depends on how much they know about their investment.
