A. This transaction decreases both current assets and current liabilities by the same amount, so total current assets will not change. However, the current ratio will change as a result of this transaction.

B. This transaction causes a decrease in cash (a current asset) and an equal increase in advances (a current asset). Therefore, this transaction has no impact on either the current ratio or current assets.

C. A cash dividend declared will not change current assets, but it will cause the current ratio to change as the company has more current liabilities than before.

D. The sale of the asset for cash will increase current assets but have no effect on current liabilities. This means that both the current ratio and the balance of current assets will change.
