Answer 1

Answer: (D)

Hugo do Vries, who worked on evening primrose

Hugo de Vries based on his work on evening primrose brought forth the idea of mutations- large arising suddenly in a population. He believed that it is mutation which causes evolution and not the minor variations (heritable) that Darwin talked about. Mutations are random and directionless while Darwinian variations are small and directional.
