Solution

The correct option is D Prolifically
Darwin concluded that organisms reproduce prolifically and in each generation the number of individual increases that can survive. The individuals show some phenotypic variations, and these variations are heritable. Darwin also suggested that the process of evolution is based on natural selection.
