Respuesta :

Answer: B

Explanation: The market portfolio, often represented by a broad market index like the S&P 500, is considered to have the greatest amount of systematic risk because it reflects the overall market fluctuations. Systematic risk, also known as market risk, is the risk that cannot be diversified away and is inherent to the entire market. Therefore, the market portfolio, representing the entire market, is exposed to the highest level of systematic risk.
