The correct answer is: Repayment of an overdraft.
An overdraft is a borrowing facility repayable on demand. The repayment of an overdraft will increase the amount of cash which is the bottom line of the statement of cash flows.
Repurchase of a long-term loan means the company is paying the loan back. Dividends paid are a financing outflow.
Issue of ordinary shares would be a cash inflow under ‘financing'.
