Answer:
Option Total assets, total liabilities, and equity are unchanged.
Step-by-step explanation:
The reason is that the double entry to record this transaction is as under:
Dr Cash Account $42,000
Cr Accounts Receivable $42,000
Hence there increase in one asset and decrease in other asset will have zero net impact on assets. As equity and liabilities are not effected by the transaction, hence they will also remain unchanged.
