Explanation:

The quick ratio (also known as the acid-test ratio) is calculated as:

$$\text{Quick Ratio} = \frac{\text{Cash and equivalents} + \text{Short-term marketable securities} + \text{Receivables}}{\text{Current liabilities}}$$

Plugging in the numbers:

$$\text{Quick Ratio} = \frac{800 + 500 + 2,000}{10,000} = \frac{3,300}{10,000} = 0.33$$

• Option A (0.13) is incorrect because it represents the cash ratio, which only includes cash and short-term marketable securities.
• Option C (0.00) is incorrect as it does not align with any standard liquidity ratio calculation.

The correct answer is B (0.33), as it accurately reflects the quick ratio.
