Answer:
The correct answer would be option A, Medicare Taxes.
Step-by-step explanation:
It is quite common now a days to work with contractors to get help from them, either in the form of services or human resources, etc. The contractor provide the company what it wants according to the needs. For example if a company needs human resource for its customer service department, the contractor will provide them the employees according to the company's need. So when you hire the contractor for getting you employees, there is no need to pay the medicare taxes of the contractor. It is not the responsibility of the company to pay medical expenses of the contractor, rather its contractor's own responsibility to fulfill its medicare expenses.
