Answer: B — 24 hours

It is important for a bus driver to thoroughly inspect their vehicle before driving it to ensure the safety of its passengers. According to the Ontario Ministry of Transportation, a bus inspection and completion of an inspection report must be conducted within 24 hours before driving a bus of any type. While options A, C, and D might seem like reasonable time frames, 24 hours is the maximum amount of time allowed for a bus inspection in order to ensure that any potential safety issues are addressed before the vehicle is used for transportation. Therefore, option B is the correct answer.
