 same as velocity 


Option: 2

same as displacement


Option: 3

same as acceleration 


Option: 4

None

 Displacement is given by the relation. 
\mathrm{s_0=3 \alpha t}     ..................(1)
Now,
Velocity \mathrm{ \frac{d S_0}{d t}=3 \alpha}
Then, 
Acceleration \mathrm{\frac{d^2 S_0}{d t^2}=0 }...............(2)

Value of  \mathrm{\left(A_0+S_0\right)=0+3 \,\alpha t }
\mathrm{ =3 \alpha t } same as dis placement.
