The correct options are
A Girl coming down on a slide.
C A car moving on a crowded road.
D Motion of an aeroplane.
Motion in which there is unequal distance covered in equal intervals of time.
In sliding of a girl down the slide, the distance covered by the girl in equal intervals of time is not fixed. Hence it's motion is of non-uniform type.
Motion of soldiers during a parade can be considered as an example of uniform motion because ideally they cover equal distance in equal intervals of time.
Motion of a car on a crowded road is also another example of non-uniform motion, as here too the distance covered in equal time intervals is different.
For the motion of an aeroplane, during each phase, such as taking off, flying, landing, plane covers different disance per unit time in each phase. Hence it is an example of non-uniform motion.
