Correct answer

A. The speed travelled

Comment

The faster you drive, the greater the air resistance acting on your vehicle. Doubling your speed results in 4 times the air resistance. The tread depth of the tyres has a major effect on the rolling resistance of the tyres. The number of passengers does not directly affect the air resistance.
