The answer is letter C. macroevolution. Macroevolution refers to an evolution of the largest scale, specifically creation of new species and extinction while Microevolution refers to a change in gene frequency within a population; molecular basis for evolution. The process of speciation may fall within the purview of either, depending on the forces thought to drive it.
