Answer:
D) Service Revenue
Step-by-step explanation:
An unearned revenue is the revenue which is generated before the services are even given to the client. It can also be called as deferred revenue. Hence the answer to this question can not be Unearned Revenue. The other two options (A & B) are also not applicable here.
Hence, it is clear that the revenue generated but yet not received will be known as the Service Revenue in the income statement.
Good Luck buddy.
