Answer:
D. A credit of $800
Step-by-step explanation:
The accumulated depreciation is the total depreciation over the years of use of an asset. It usually has a credit balance.
Hence where Accumulated Depreciation has a balance of $600 in the Unadjusted Trial Balance column and an adjustment of $200 in the Adjustments Credit column, the total balance in the Adjusted Trial Balance column is the sum of the two credits
= $600 + $200
= $800 (credit)
