The correct answer is:c
Statement I is correct but Statement II is incorrect
Explanation: Statement I suggests that decreasing the length of the sample tube decreases the magnitude of optical rotation. This is a valid statement because the length of the sample tube can influence the optical rotation of polarized light passing through an optically active substance. 
However, Statement II states that decreasing the length of the sample tube decreases the contribution of the sample tube material to the total optical rotation. This is not necessarily true. The contribution of the sample tube material to optical rotation depends on factors such as the specific optical properties of the material and the length of the tube. Simply decreasing the length of the tube does not necessarily decrease the contribution of the material, as it depends on the nature of the material itself.

Statement I: Decreasing length of sample tube, while keeping everything else intact, decreases the magnitude of optical rotation.
Statement II: Decreasing length of sample tube decreases the contribution of sample tube material to the total optical rotation.

Explanation:
The optical rotation is a phenomenon in which the plane of polarized light rotates when it passes through certain substances. It is measured using a polarimeter, which consists of a light source, a polarizer, a sample tube, an analyzer, and a detector.

Statement I: Decreasing length of sample tube, while keeping everything else intact, decreases the magnitude of optical rotation.

When light passes through a substance in a sample tube, it interacts with the molecules of the substance. The interaction between the light and the molecules causes the plane of polarization to rotate. The magnitude of the rotation is directly proportional to the length of the sample tube.

When the length of the sample tube is decreased, the interaction between the light and the molecules is reduced, resulting in a decrease in the magnitude of optical rotation. This is because the light has less distance to travel through the substance, so it interacts with fewer molecules.

Statement II: Decreasing length of sample tube decreases the contribution of sample tube material to the total optical rotation.

The sample tube itself can also contribute to the overall optical rotation. The sample tube material may have its own optical properties, such as birefringence or optical activity, which can affect the rotation of the polarized light passing through it.

When the length of the sample tube is decreased, the contribution of the sample tube material to the total optical rotation also decreases. This is because there is less sample tube material for the light to interact with, resulting in a reduced contribution to the overall rotation.

Conclusion:
Both Statement I and Statement II are correct. Decreasing the length of the sample tube decreases the magnitude of optical rotation, and it also decreases the contribution of the sample tube material to the total optical rotation. However, Statement II is not the correct explanation of Statement I. The decrease in the magnitude of optical rotation is primarily due to the reduced interaction between the light and the molecules of the substance, rather than the decrease in the contribution of the sample tube material. Therefore, the correct answer is option 'C' - Statement I is correct but Statement II is incorrect.
