The appropriate ratio for indicating liquidity crisis is

Operating ratio
Sales turnover ratio
Current ratio
Acid test ratio

The correct answer is D. Acid test ratio.

The acid test ratio, also known as the quick ratio, is a liquidity ratio that measures a company’s ability to pay off its short-term obligations with its most liquid assets. It is calculated by dividing a company’s current assets minus its inventory by its current liabilities.

A high acid test ratio indicates that a company has a good liquidity position and is able to meet its short-term obligations. A low acid test ratio indicates that a company may have difficulty meeting its short-term obligations.

The operating ratio is a profitability ratio that measures how efficiently a company uses its assets to generate sales. It is calculated by dividing a company’s operating expenses by its net sales.

A high operating ratio indicates that a company is not using its assets efficiently to generate sales. A low operating ratio indicates that a company is using its assets efficiently to generate sales.

The sales turnover ratio is a profitability ratio that measures how many times a company sells its inventory in a year. It is calculated by dividing a company’s net sales by its average inventory.

A high sales turnover ratio indicates that a company is selling its inventory quickly. A low sales turnover ratio indicates that a company is not selling its inventory quickly.

The current ratio is a liquidity ratio that measures a company’s ability to pay off its short-term obligations with its current assets. It is calculated by dividing a company’s current assets by its current liabilities.

A high current ratio indicates that a company has a good liquidity position and is able to meet its short-term obligations. A low current ratio indicates that a company may have difficulty meeting its short-term obligations.
