The correct answer is A. sales tax.
First of all, we need to determine what a paystub is. It is actually just another way to say paycheck, or the money you receive from your employer for the work you've performed during the previous month.
However, there are some taxes that are deducted from your paycheck before you actually receive it - these taxes include social security tax, state income tax, as well as Medicare tax. What they don't include is sales tax - which is a tax you pay when you buy something.
