To obtain a bus license C or F you must already hold what class of license?

Answer: C — G

To obtain a bus license C or F, one must possess a class G license. This is because a class G license allows the driver to operate any motor vehicle, including a bus, that has a seating capacity of over 24 passengers. Options A, B, and D are incorrect because they do not pertain to the specific class G license required for operating a bus. Option A, obtaining a license F, would not automatically grant a class G license as they are separate classifications. Option B, obtaining a license E, would only allow for the operation of a single-axle motor vehicle and would not cover the capacity or type of vehicle needed for a bus license. Option D, obtaining a license D, is also incorrect as it does not cover the specific class G license required for operating a bus.
