Answer:
D. $0
Step-by-step explanation:
Unearned revenues are a liability (permanent account), therefore, they cannot be included in the income statement.
E.g. Journal entry to record unearned service revenue
Dr Cash 50,000
Cr Unearned revenue 50,000
Unearned revenue will continue to be a liability until the earning process is completed, then the liability is cancelled and revenue is recognized.
E.g. Journal entry to record accrued revenue
Dr Unearned revenue 50,000
Cr Service revenue 50,000
