Solution

The correct options are
A Natural selection
B Speciation
C Inheritance of characters
Evolution, in simple terms, means the change in the heritable characteristics of a group of organisms over many generations. These heritable changes could be due to natural selection, inheritance of characters or mutations. Thus, evolution leads to the formation of new species.
