Answer:
Option A is the correct answer ,debit cash with $1000 and credit accounts receivable with the same amount.
Explanation:
Since the company uses accrual basis of accounting,which implies that revenue is recognized when earned not when cash is received.
Besides,revenue would have been recorded earlier by debiting accounts receivable and crediting revenue,which means that the receipt of cash now has no entry in revenue since revenue has been recorded previously.
The cash receipt would have impact in cash account as an increase and a debit as well as accounts receivable as a decrease and a credit.
