What type of motion is represented by following displacement-time graphs

The displacement – time graph of a body in motion is given as shown in figure the velocity of the body is (in m/s)

A force-displacement graph will include displacement in all directions.

What can you say about the nature of motion of a body if its displacement-time graph is(a) a straight line parallel to time axis?(b) a straight line inclined to the time axis with an acute angle?(c) a straight line inclined to the time axis with an obtuse angle?(d) a curve?

What is the nature of the distance-time graph for accelerated motion?

Which of the following speed-time graphs exist in the nature?ABCDAll of the above
