Answer:
b) inventory is sold on credit.
Explanation:
Liquidity is defined as the a business to use its current assets to settle it's current liabilities.
This is calculated by using the working capital ratio.
Working capital ratio = Current assets ÷ Current liabilities.
Cash and inventory contribute to a business' liquidity.
When inventory is sold on credit, it does not result in immediate increase in cash as payment is in the future. So there is a reduction in the current asset of the company.
A reduction in the numerator of the working capital ratio results in lower value of the ratio (lower liquidity)
