Answer: b. Luncheon is served.
Step-by-step explanation:
The Accrual Basis in Accounting requires that Revenues are recorded when they are earned as well as Expenses being recorded when incurred. Revenue is not to be recorded when the services have been paid for when when an order has been made. They are to be recorded when the service has been fulfilled or the goods delivered.
In the above case, ABC is a caterer and their main business is to serve business luncheons for large corporations.
This means that their service is done when they serve these luncheons. This should be when the revenue should be recognized then because this is when their service was delivered.
