Which of the following are liquidity ratios? I. cash coverage ratio II. current ratio III. quick ratio IV. inventory turnover

Cash coverage ratio,current ratio and quick ratio are liquidity ratios.Inventory turnover is not a liquidity ratio,but inventory turnover ratio is.

Explanation:

Cash coverage ratio compares the cash and those items that are readily convertible cash to pay company's liabilities,so as to find out whether liquid resources available in form of cash and cash equivalents are enough to settle short-term obligations.

Current ratio  compares company's total current assets to total current liabilities to establish the ease of settling short-term liabilities with short-term assets.

Quick considers how easy it is to pay short-term liabilities with current assets without the inventory,since inventory is the most difficult to convert to cash.
