Which of the following is NOT an aspect that we can learn from remotely observing another planet or moon?

A) how they reflect different types of electromagnetic energy, such as ultraviolet
B) whether their surface is smooth or rough
C) how quickly a surface cools off
D) whether a rock contains fossils

Remote observation techniques allow scientists to study the reflection of electromagnetic energy, surface textures, and thermal properties of celestial bodies. However, determining the presence of fossils requires direct sampling or more detailed analysis than what remote sensing can typically provide, as it involves the study of specific organic structures within rocks.
