How does natural selection lead to evolution

What were the three key observations made by Darwin that allowed him to deduce that natural selection is a primary driver of evolution?Group of answer choicesSpecies change due to the next generation inheriting genes based on their parent's behaviors.Gene flow and mutations provide the right changes for future generations to thrive.Organisms produce more offspring than survive, variation exists among individuals, and advantageous variations increase in relative frequency over time.The number of adults tends to remain the same over time, individuals vary little over time, and natural selection works on only the best of those adults in each generation.
