Which of the following does not qualify as a contingent liability?

Explanation

A contingent liability refers to a potential obligation that depends on the outcome of future uncertain events. Doubtful debts represent amounts owed by debtors that may not be fully collectible, but this uncertainty is related to the realization of the asset rather than the existence of a liability; therefore, they are not contingent liabilities but require provision for bad debts. On the other hand, uncalled liabilities on partly paid shares (option B), disputed claims not acknowledged as debts (option C), and arrears on fixed cumulative dividends (option D) all depend on future events and thus qualify as contingent liabilities.
