The term "capital gains tax" refers specifically to the taxation applied to profits gained from the sale of capital assets, such as stocks, real estate, or other investments. When an individual sells a capital asset for more than its purchase price, the profit made from that transaction is considered a capital gain. This gain is subject to taxation, hence the term "capital gains tax."

The correct answer recognizes that this tax is tied explicitly to the financial result of selling assets, distinguishing it from other types of income. In contrast, the other options describe different forms of taxation. For instance, a tax on all income regardless of source would encompass more than just capital gains, while a tax specifically for charitable donations does not relate to capital assets at all. Similarly, a tax on employment earnings only pertains to wages and salaries, excluding capital assets from its scope. Therefore, the essence of capital gains tax lies in its application to profits derived from capital assets, which is succinctly captured in the correct choice.
