Answer:
The correct answer is c. the truck driver.
Any object is said to be the motion if its relative distance with respect to a reference point is keep on changing.
For example, a kid travelling through a train might seem to be stationary with respect to the seat. However, he would seem to be moving if we see him in respect to the railway track outside the train.
A reference point is anything (place, person or any object) used to determine if something or someone is in motion.
In the given situation, the distance between truck driver and bulldozer will remain the same throughout the journey as it is being placed on the back of the truck. Hence, the correct answer is truck driver.
The reference point where the bulldozer does not appear to be moving is:
According to the given question, we can see that there is a bulldozer which is moving at a speed of 50km/h to the back of a flatbed truck.
As a result of this, we can see that the truck driver is in front of the bulldozer and as the object is in motion, then the reference point would keep changing.
The reason why the reference point of the driver would appear to be stationary is that he is placed at the back of the truck.
Therefore, the correct answer is option C
