A container having a hole at the bottom is free to move on a horizontal surface. As the liquid comes out, the container with an acceleration $\mathrm{\alpha }$ and finally acquires a velocity v ( when the liquid has drained out). Neglect the mass of container. The correct option out of the following is:
 

• A

  only v depends on h

• B

  only $\mathrm{\alpha }$ depends on h

• C

  both v and a depend on h

• D

  neither v nor $\mathrm{\alpha }$ depends on h
