Answer:
D. Progressive taxation
Explanation:
Progressive taxation is a taxing method whereby the tax collected increases as the taxable amount increases. The tax rate progresses as the taxable income progresses. It is the proportional rise in the amount of tax paid due to increases in income. By arguing that the rich should not be taxed at a higher rate just because they make more money, Mark is arguing against Progressive taxation which points to the higher you earn, the higher amount of tax you pay.
