Explanation

Solvency ratios measure a company's ability to meet its long-term obligations and continue operations over the long term. They assess the company's financial leverage and ability to pay interest and principal on debt.

Analysis of each option:

1. Quick ratio (Option A) - This is a liquidity ratio, not a solvency ratio. It measures a company's ability to meet short-term obligations using its most liquid assets (cash, marketable securities, and receivables).

2. Current ratio (Option B) - This is also a liquidity ratio. It measures a company's ability to pay short-term obligations using current assets.

3. Interest coverage ratio (Option C) - This is a solvency ratio. It measures a company's ability to pay interest expenses on outstanding debt. It's calculated as:

   $$\text{Interest Coverage Ratio} = \frac{\text{EBIT}}{\text{Interest Expense}}$$

   A higher ratio indicates better ability to meet interest obligations.

Other common solvency ratios include:

• Debt-to-equity ratio
• Debt-to-assets ratio
• Financial leverage ratio
• Fixed charge coverage ratio

Conclusion: Among the given options, the interest coverage ratio is the only one that measures solvency rather than liquidity.
