ok! what does that mean? :/ pitch gets lower?

since the source of the sound is going away from me, then the received frequency from me, is less than the emitted frequency by the truck

ohh so the solution should be amplitude is lower? choice D?

I think that the answer is the pitch gets higher, since we have the subsequent relationship between wave length and frequency: \[\Large \lambda = \frac{v}{\nu }\] where v is the speed of sound
