Question

V = u + at is the equation of motion the deseribing relation between .......................
1)displacement of velocity
2)displacement of time
3)velocity and time
4)velocity and acceleration

Answer 1

Option d)- velocity and acceleration

Answer 2

V=u+at is the first equation of motion where,
V=final velocity 
u=initial velocity
t=time
a=acceleration.

As acceleration is rate of change of velocity:
a=v-u/t

Hence 
First equation of motion , V=u+at  describes the relation between Velocity and acceleration.
option d
