The theory of evolution will be best supported by the evidence showing a species changes over time. Thus, option A.
Basic evidences for proving the theory of evolution are anatomy, Biological morphology, Fossils and direct observations. There have been various theories for the proof of evolution like structural similarities in an embryo formation pointed towards common ancestors. Theory of Natural selection embarked by Charles Darwin to show genetic variations picked by organisms in whole population.
The most authentic theory over evidence for evolution is Paleontological theory which includes study, observation and acquired prove of fossils of various organisms in the forms of Petrified, mold and cast, trace fossils, compression fossils, impression fossils, etc.
