Answer:
C. Increases Supplies Expense $750 and decreases Supplies $750
Explanation:
We assume that the balance on Supplies account of $1,350 should have been $600 and Supplies Expense with balance $0 should have been $750.
The corrective entry for this error will be to reduce the supplies account by $750 and increase the supply expense account by $750.
Therefore the following entry is required.
Supply Expense debit $750 (Increase )
Supplies credit $750 (Decrease)
Hope that helps.
