Answer: a. Prepaid expenses
Step-by-step explanation:
Prepaid expenses are payments made for expenses that have not been incurred yet. In other words, the company is paying in advance for expenses it will incur in future.
By paying $3,000 towards work to be done on their landscaper even though work has not started yet, the company is paying for an expense it will incur in future so the relevant adjustment is Prepaid expenses.
