Which of the following is a profitability metric that assesses performance across net income and sales?

• A. Net profit margin
• B. Current ratio
• C. Return on assets
• D. Debt-to-equity ratio

Answer: (C)

Profitability measures look at how effectively a business turns sales into earnings and, in doing so, how efficiently it uses its resources. Return on assets shows net income per dollar of assets, so it reveals how much profit the company generates for each unit of capital invested. Because assets underpin production and sales, ROA combines the outcome (net income) with the resource base (assets) to gauge overall profitability efficiency.

The other metrics don’t capture that same combination. Net profit margin ties profit directly to sales, indicating profit per dollar of revenue but not how assets are employed. The current ratio is a liquidity gauge, not profitability, and the debt-to-equity ratio assesses financial leverage rather than earnings efficiency.
