Explanation:

- Option 1: Within a year

- Current liabilities are obligations a company is expected to settle within one year. They include items like accounts payable, short-term debt, and accrued liabilities.

- This is the correct answer.

- Option 2: After one year but within five years

- Typically, obligations due after one year fall under long-term liabilities, not current liabilities.

- Option 3: Within five years

- Current liabilities need to be settled much sooner. This option aligns more with certain long-term liabilities.

- Option 4: Subject to a contingency

- Contingent liabilities depend on the outcome of future events. They aren't necessarily payable within a year.
