When a capillary tube is dipped in a liquid, the liquid rises to a height h in the tube. The free liquid surface inside the tube is hemispherical in shape. The tube is now pushed down so that the height of the tube outside the liquid is less than `h`. Then

A

the liquid will ooze out of the tube slowly

B

the liquid will come out of the tube like in a small fountain .

C

the liquid will fill the tube but not come out of its upper end .

D

the free liquid surface inside the tube will bot be hemispherical
