Solution

The correct option is B Variations
Darwin and Mendel worked simultaneously but Darwin was unaware of Mendel's theory of inheritance. He was not aware of origin of variations in populations. Neo Darwinism is an attempt to explain Darwin's work in light of modern theory of inheritance, which explains the presence of variations in sexually reproducing natural population.
