Introduction:
Change in resistivity refers to the change in the electrical resistance of a material. It is a property that can be measured and is influenced by various factors such as temperature, radiation, and moisture content. In this case, all of the mentioned options can be measured using change in resistivity.

Explanation:
1. Temperature:
Temperature has a significant effect on the resistivity of a material. As the temperature of a material increases, the resistance also increases. This is because at higher temperatures, the atoms in the material vibrate more vigorously and collide with the moving electrons, causing more obstacles for the flow of current. This increase in resistance can be measured by the change in resistivity.

2. Visible radiation:
Visible radiation, or light, can also affect the resistivity of certain materials. When light interacts with a material, it can cause the excitation of electrons and create charge carriers, leading to a change in the electrical properties. This change in resistivity due to visible radiation can be measured.

3. Moisture content:
Moisture content refers to the amount of water present in a material. Water is a good conductor of electricity, and its presence can alter the resistivity of a material. When the moisture content increases, the resistivity decreases as water provides more conductive paths for the flow of current. Conversely, a decrease in moisture content leads to an increase in resistivity. Therefore, measuring the change in resistivity can help determine the moisture content of a material.

Conclusion:
In conclusion, the change in resistivity can be measured to determine various properties such as temperature, visible radiation, and moisture content. By analyzing the change in electrical resistance, it is possible to understand the influence of these factors on the material under consideration.
