Answer: d. progressive
Explanation:
In a Progressive tax regime, taxes are paid based on the taxable amount of the taxpayer. The higher the taxable amount, the higher the tax rate paid.
In this scenario, the tax rates are;
Household A = 10,000/50,000 = 20%
Household B = 50,000/200,000 = 25%
Household B is paying a higher tax rate because they earn more making this a progressive regime.
