The answer is: D. w-4
The w-4 form requires you to fill several crucial information that is relevant in order to count the tax that you owed to the federal government. (such as your salary, social security numbers, whether you are married or not, the number of your dependents, etc)
After the data is submitted to the government, they would automatically cut off the tax that you owed to the government every time your employer pay your salary.
