To avoid compromising your car's aerodynamic properties, you should avoid . running your air conditioning system b. taking turns at high speeds c. carrying large loads on the outside of the vehicle

C) True   carrying large loads on the outside of the vehicle

Explanation:

The aerodynamic property of an object depends on its outer shape. In general, objects should be thin in the front and not completely flat in the back, to avoid the eddies that create a great Arrate, losing all the aerodynamics of the system.

With this we can review the final statements

A) False The air conditioner is used with the glasses raised, so the exterior shape of the car does not change and its aerodynamics remains unchanged.

B) Phallus. This does not change the outer shape, I get a small inclination,

C) True. External loads dramatically change the external shape of the vehicle significantly reducing its aerodynamic characteristics.
