Answer:
We know that slope of Velocity-Time graphs gives the acceleration.
Positive slopes give acceleration and negative slopes give retardation.
From the First graph, It is upward parabola ⇒V=V
0

,
dt
dV
=2t ⇒
dt
dV
>0 so it gives acceleration.
From the Second graph, it is downward parabola ⇒S=S
0
−t

⇒

dS
=−2t=V ⇒

dV
=−2 which is retardation.
From the third graph, acceleration is increasing clearly.
From the Fourth graph, S=C Where C is constant, ⇒
dt
dS
=0=V ⇒
dt
dV
=0, Acceleration is zero.
Only seconds graph gives retardation.
