Answer: B - Road, traffic, weather, vehicle size, night driving, noise, vibration, and type of cargo

Bad road conditions, traffic, weather and night driving require more attention and concentration. Vehicle size demands more physical effort. Noise and vibration result into a number of musculoskeletal disorders. Some cargo may be by nature hazardous to health if the driver is directly exposed to it. Answers A and C are both wrong because shape of cargo, tires’ condition and attitude of passengers are insignificant to the driver’s health and both answers missed other important factors.
