In the figure below is shown the flow of the liquid through a horizontal pipe. Three tubes A, B and C are connected to the pipe. The radii of the tubes A, B and C at the junction are respectively 2 cm, 1 cm and 2 cms. It can be said that

• A. the height of the liquid in the tube A is maximum
• B. height of the liquid in the tube A and tube B is the same
• C. height of the liquid in all the three tubes is the same
• D. height of the liquid in tube A and C is the same
