Answer:
The correct answer is Debit Unearned Plowing Revenue
Explanation:
Earlier the journal entry would be recorded as:
Cash A/c.................................................Dr $4,000
Unearned Plowing Revenue A/c..............Cr $4,000
But the correct entry that should be recorded is:
Cash A/c.................................................Dr $4,000
Plowing Revenue Earned A/c..............Cr $4,000
So, in order to pass the adjusting entry, we should debit the Unearned Plowing Revenue in order to reconcile or nill the same account by debiting.
