Natural selection is the primary process that drives Darwin's theory of evolution, the correct option is a.
Darwin's theory of evolution is primarily driven by the process of natural selection. Natural selection is the mechanism by which certain heritable traits become more or less common in a population over successive generations. It occurs due to the differential reproductive success of individuals with advantageous traits that are better suited to their environment. Individuals with beneficial traits are more likely to survive and reproduce, passing on their advantageous traits to their offspring.
Over time, this leads to the accumulation of favorable traits within a population, while less advantageous traits become less prevalent. Natural selection is driven by various factors, including environmental pressures, competition for resources, and adaptation to changing conditions. It is a key driving force behind the diversity and adaptation of species observed in the natural world, the correct option is a.
