Final answer:
Contingent liabilities are unique because they depend on the result of a future event.
Step-by-step explanation:
A. Whether or not a company has an obligation depends on the result of a future event.
Contingent liabilities are considered unique and different from all other liabilities because they are dependent on the occurrence or non-occurrence of a future event. This means that a company may or may not have an obligation depending on what happens in the future.
For example, a company may be involved in a lawsuit, and the outcome of the lawsuit will determine whether or not the company has a liability. If the company loses the lawsuit, it will have a contingent liability.
Therefore, the correct answer is A. Whether or not a company has an obligation depends on the result of a future event.
