Answer:
The incorrect statement regarding relevant costs and revenues:
To be relevant, a cost or revenue must not be future-oriented and must differ between the alternatives.
Step-by-step explanation:
For a cost or revenue to be considered as relevant, it must be incurred or earned at a future time. It must also differ between the options available for decision making. A cost or revenue cash flow is relevant if it arises from a management decision and can be avoided. This simply means that if the cost or revenue is not affected by management decision or does not make any difference in decisions, it is not relevant.
