B) If both the assertion and reason are true but reason does not explain the assertion.
C) If assertion is true but reason is false.
D) If assertion is false but reason is true.
Correct Answer: D
Solution :
\[h=\frac{T}{Rdg}\Rightarrow hR=\frac{2T}{dg}\] \[\therefore \] \[\text{hR}\]= constant Hence, when the tube is of insufficient length, of curcature ratius of the liquid meniscus increases, So, as to maintain the product hR a finite constant. i.e. as h decrease, R increase and the liquid meniscus became more and more flat, but the liquid does not over flow.
