Answer

Brief Explanations:

According to the Doppler - effect, when the observer (in the train) is moving towards the source of sound, the frequency (pitch) of the sound reaching the observer is higher than the source frequency. Here the train is accelerating (moving towards the source in a general sense of relative motion for sound - wave reception), so the pitch should be higher, not lower.

FALSE
