Within the CAPM framework, beta quantifies the degree of systematic risk relative to the market portfolio, which by definition has a beta of 1. A portfolio with a beta greater than 1 carries more systematic risk than the market, meaning its returns are expected to be more sensitive to market movements. This higher sensitivity increases both upside potential and downside exposure. According to CAPM, investors require a higher expected return for bearing this additional risk. Importantly, a higher beta does not guarantee superior performance; it simply reflects greater volatility relative to the market. Option B accurately captures this risk-based interpretation.
