Answer
Option A is correct.
The amount of gas in a car's gas tank over a distance driven.
Step-by-step explanation
The graph shows that the amount on the y-axis decreases as the quantity on the x-axis increases.
So,
The mileage of a car, the amount of gas used by a car and the temperature of a car cannot all increase as the distance over which the car is driven increases.
The only quantity that can decrease as the distance increases is tge amount of gas in the gas tank because the amount of gas in the gas tank reduces as distance driven increases.
So, this is the relationship represented by the graph attached.
