Answer: a. At the end of Year One, the company's liabilities are understated.
Step-by-step explanation:
Under the Accrual basis of Accounting, revenue should be recorded for only jobs that have been completed. In other words, only earned revenue should be recorded. Revenue that has not been earned but yet received, is to be termed Deferred revenue and should be treated as a current liability.
In this scenario, there are steps that have not been completed so some of the revenue received should be termed deferred revenue. These should therefore be in current liabilities and because they were not, the liabilities for the end of year 1 will be understated.
