Solution

The correct option is A
True

Darwin's theories did not provide a proper explanation regarding the sources of variation. Later, the information regarding the sources of variation provided by Mendel was combined with Darwin's theory of natural selection which gave rise to the concept of Neo Darwinism, which was a modified and the modern version of Darwinism.
