Final answer:
Temperature is not a physical property used to distinguish between soil types; rather, texture and color are. Temperature varies based on external conditions and does not reflect an inherent characteristic of the soil. The correct answer is option b.
Step-by-step explanation:
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. In the context of soil types, texture and color are examples of physical properties that help distinguish between different soil types. However, temperature is not a physical property used to distinguish soil types, as it is variable and depends on external conditions rather than the soil's inherent characteristics.
