The _____ ratios are primarily measures of return.

The correct answer is Option (4) → Profitability

Ratios fall into four groups: liquidity (short-term payments), solvency or debt (long-term payments), activity (speed of turnover) and profitability. Only profitability ratios, such as net profit ratio and return on investment, measure the return the business earns on its sales or on the capital employed.
