D. Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. Like the arthralgus of a whale that looks very similar to a terrestrial mammals tells us that the whale evolved from land mammals
C. Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.
