d.It ignores the risk-free rate entirely

The Sharpe ratio divides a portfolio's excess return over the risk-free rate by its standard deviation, measuring reward per unit of total risk. A higher ratio indicates better risk-adjusted performance. The Treynor ratio, by contrast, uses beta as the risk measure.
