Answer:
The correct answer is letter "A": sell; keep.
Explanation:
Only when an asset is sold it is possible to find out if we took profit or loss from it. The after-tax gains are higher than the selling price when the taxpayer sells assets that have decreased in value because the loss lowers taxes due. On the other hand, when a valued asset is sold, the after-tax proceeds are lower than the selling price due to the gain tax.
