Answer:
a.Cash is increased, and unearned rent is increased.
Step-by-step explanation:
Since in the question, it is mentioned that QRT Co. received $1,560 advance from Zync Inc. for the building use.
We know that the cash is received which increases the cash balance but the service is not provided so it would become a liability and recorded as unearned rent.
The unearned rent is increased which show under the current liability side of the balance sheet
Hence, both cash and unearned rent is increased
