Answer: 21%.

The correct answer is **B (21%)**. **Explanation:** The debt-to-capital ratio is calculated as: \[ \text{Debt-to-Capital Ratio} = \frac{\text{Total Debt}}{\text{Total Debt} + \text{Total Shareholders' Equity}} \] - **Total Debt** includes short-term interest-bearing debt (700), current portion of long-term interest-bearing debt (500), and non-current portion of long-term interest-bearing debt (800), summing to **2,000**. - **Total Shareholders' Equity** is **7,500**. Thus, the calculation is: \[ \frac{2,000}{2,000 + 7,500} = \frac{2,000}{9,500} = 0.211 \text{ or } 21\% \] **Why not A or C?** - **A (17%)** excludes the current portion of long-term interest-bearing debt, leading to an incorrect total debt of 1,500 and a ratio of 17%. - **C (27%)** incorrectly calculates the debt-to-equity ratio instead of the debt-to-capital ratio, resulting in 27%.
