Answer:
c. historical cost minus accumulated depreciation.
Explanation:
As we know that
The plant asset is a fixed asset which is to be shown in the asset side of the balance sheet
For computing the book value of a plant asset we deduct the accumulated depreciation from the historical cost or the purchase price or the acquired cost
In mathematically,
Book value of a plant = Historical cost - accumulated depreciation
The accumulated depreciation is a depreciation expense which should be cumulative
