Let a thin capillary tube be replaced with another tube of insufficient length then ,we find water.
(A). Will overflow
(B). Will not rise
(C). Depressed
(D). Change its meniscus

Hint: When liquid enters the capillary tube then suddenly its pressure drops and due to this sudden drop of pressure the liquid rises in the tube without any external effort and even against the force of gravity .The phenomenon is known as capillarity and this capillary action is dependent on the length of the capillary tube and the cross sectional area (inside diameter of the capillary tube).
So to raise the water in the capillary tube we should have proper inside diameter as well as proper length.

Complete step-by-step solution -
Here it is given that the replaced tube (replaced with the capillary tube) has sufficient length, so due to insufficient length of the pipe we will not be getting proper pressure due to which the liquid will rise.
Hence answer to this question will be,
If we replace a capillary tube with a pipe of insufficient length then water will not rise in the tube.
So this pipe which is being replaced by the capillary tube will not work as a capillary tube at all because it will not perform the capillarity that is capillary action due to its insufficient length.
So to make this work we have to choose the capillary tube or we can choose the pipe which is having the exact or appropriate dimension (length and the internal diameter) as that of the capillary tube.
Hence the option (B) is the correct answer.

Note: This principle related to the capillary tube is also used in the refrigeration system, in the refrigeration system, then there is a sudden drop when the refrigerant leaves the condenser and enters the capillary tube of the thermal expansion valve. This happens due to the very small diameter of the capillary tube.
