The answer is C - differences between organisms.
Fossils provide evidence of past life and help us understand how organisms have changed over time. They can help us determine the physical characteristics and behaviors of ancient organisms.
Genes provide information about the genetic makeup of organisms, including differences between species. By studying genes, we can determine how closely related different species are and how they have evolved over time. This information can be used to better understand the relationships between different organisms and their genetic differences.
