Option D.The decrease in the value of the car, which is 8%
Step-by-step explanation:
we have a exponential function of the form
where
y is the value of the car
x is the time in years
a is the initial value
b is the base
r is the rate of decrease
b=1+r
In this problem we have

0.92=1+r
r=0.92-1=-0.08=-8%-----> is negative because is a rate of decrease
