The correct answer is option B which is a chainsaw, diesel truck, rustling leaves.
<h3>Explanation:</h3>
The amplitude of the sound wave is the maximum displacement of the particles from their resting position.
Higher the amplitude means high sound.
So the sound of a chainsaw is high, so its amplitude will be great and after that the amplitude of diesel truck is high and rustling leaves have the lowest amplitude.
In fact, this option lists the sounds from greatest amplitude (which means, greatest loudness) to smallest amplitude. For comparison, this is the intensity of the three different sounds: - chain saw: approximately 120 dB - diesel truck: approximately 80 dB - rustling leaves: approximately 20 dB

This does not violate Newton's 1st law because the net force would still be 0 in order to produce uniform motion (aka constant velocity). The other forces acting on the vehicles is air resistance which is non-zero. So we need car internal force to counter balance this force, which require extra gas for the car.
