解释：

Solution

A is correct. Model risk is the risk of using the wrong model to analyze an investment or the risk of using the right model for the analysis but using it incorrectly. Tail risk, although it involves unlikely but substantial losses, typically results from using inappropriate modeling assumptions such as assuming that returns are normally distributed. Credit risk involves the risk of a borrower not repaying you, whereas solvency risk is the risk of you running out of the money needed to pay your obligations. Liquidity risk is the risk that the future transaction price for an investment will be different than expected, whereas operational risk includes a wide range of potential problems occurring within an organization’s personnel and systems.

B is incorrect because liquidity risk is the risk that the future transaction price for an investment will be different than expected, whereas operational risk includes a wide range of potential problems occurring within an organization’s personnel and systems.

C is incorrect because credit risk involves the risk of a borrower not repaying you, whereas solvency risk is the risk of you running out of the money needed to pay your obligations.
