The odometer tells you.

A. how far your vehicle has traveled in its lifetime

B. the amount of exhaust your vehicle is emitting

C. if your vehicle's filters need to be replaced

D. if your air conditioning needs to be fixed

A. how far your vehicle has traveled in its lifetime

Step-by-step explanation:

The odometer is a device on your vehicle dashboard which displays the total distance traveled by the vehicle during its lifetime. Several odometers do have the facility to reset it to 0 to enable us to determine the distance traveled since a particular event.

Odometer does not track amount if vehicle exhaust or the lifetime of vehicle's filters or air conditioning.

So among the given options, option A is correct.

A. An odometer measures the miles your car has traveled.
