Working capital management focuses on short-term assets and liabilities to ensure a business has enough cash and liquid assets to meet its short-term obligations. Effective management of working capital directly impacts liquidity, allowing an organization to maintain operational stability.

Let’s analyze each option:

Option A: Liquidity.

Correct.

Liquidity refers to an organization’s ability to meet its short-term obligations, such as payroll, supplier payments, and operational expenses.

Working capital management ensures sufficient cash flow and current assets to cover immediate liabilities, making liquidity the primary concern.

Option B: Profitability.

Incorrect.

While working capital impacts profitability (e.g., through cost control and investment decisions), profitability is more related to revenue and cost management, not just liquidity.

Option C: Solvency.

Incorrect.

Solvency refers to a company's long-term financial stability and its ability to meet debts over time.

Working capital is a short-term financial measure and does not directly determine solvency.

Option D: Efficiency.

Incorrect.

Efficiency relates to resource utilization and operational effectiveness, which are indirectly affected by working capital management but are not its primary focus.

Thus, the verified answer is A. Liquidity.
