Given below are two statements:
**Statement I:** The contact angle between a solid and a liquid is a property of the material of the solid and the liquid as well.
**Statement II:** The rise of a liquid in a capillary tube does not depend on the inner radius of the tube.
In the light of the above statements, choose the correct answer from the options given below:
Answer: (A) Statement I is true but Statement II is false.
**Statement I** is true: the contact angle depends on the pair of materials in contact.
**Statement II** is false: $h = \dfrac{2T\cos\theta}{r\rho g}$, so the rise is inversely proportional to the inner radius.
