Water rises to a height h in capillary tube. If the length of capillary tube above the surface of water is made less than h, then
  1. A
    water rises upto a point a little below the top and stays there.
  2. B
    water does not rise at all.
  3. C
    water rises upto the tip of capillary tube and then starts overflowing like a fountain.
  4. D
