Explanation:

Market risk is best classified as financial risk because:

1. Financial risk refers to risks that arise from financial market activities and affect the value of financial instruments. This includes:

   • Interest rate risk
   • Currency risk
   • Equity price risk
   • Commodity price risk

2. Market risk specifically involves the risk of losses in positions arising from movements in market prices, which is a core component of financial risk.

Why the other options are incorrect:

• Longevity risk (Option B): This is an insurance/actuarial risk related to people living longer than expected, affecting pension funds and insurance companies. It's not primarily a financial market risk.

• Accounting risk (Option C): This refers to risks related to accounting practices, financial reporting, or compliance with accounting standards. While it can have financial implications, it's more of an operational/regulatory risk rather than a pure financial market risk.

Key Distinction: Financial risks are those that can be directly measured and managed through financial instruments and market activities, whereas longevity and accounting risks are more operational or actuarial in nature.
