Answer:
(d) You will still have more money, even after taxes, than you would have in a lower tax bracket.
Step-by-step explanation:
You want to know the financial result if you move into a higher tax bracket.
In the US, the income tax rate increases as income increases. Those with income below a certain level may pay 10% of their taxable income, while above a certain level, the tax rate may be as much as 37% of taxable income. Even so, increased income results in increased after-tax income.
Thus, in moving to a higher tax bracket, you will still have more money, even after taxes, than you would have in a lower tax bracket — choice D.

Additional comment
The attached graph shows the after-tax income as a function of taxable income using the 2023 US income tax brackets for a single filer.
You will notice the slope is positive everywhere, meaning you still take home more income even after moving to a higher bracket. The "tool-tip" indicates someone with taxable income of $600,000 would have an after-tax income of about $417,668. In this highest tax bracket, you get to keep $0.63 of every taxable dollar.
