The figure shows a velocity-time graph of a particle moving along a straight line. The correct displacement-time graph of the particle is shown as:

The velocity-time graph for two bodies $A$ and $B$ is shown. Then the acceleration of $A$ and $B$ are in the ratio:

The graph of displacement $s$ versus time $t$ is given below. Its corresponding velocity-time graph will be:

The velocity versus time graph of a body moving in a straight line is as shown in the figure below.

Given below are two statements:
Statement $I:$ Area under velocity-time graph gives the displacement of the body in a given time.
Statement $II:$ Area under acceleration-time graph is equal to the change in velocity in the given time.
In the light of given statements,choose the correct answer from the options given below.

Draw the $x-t$ graphs which represent positive,negative,and zero velocity.
