Solution
The correct options are
A Mutations
B Sexual reproduction
C Gene flow
Genetic variation is the difference in DNA sequences between individuals within a population
Mutations are changes in the DNA. A single mutation can cause a large effect. In many cases, evolutionary changes are based on the accumulation of many mutations.
Gene flow is any movement of genes from one population to another.
Sexual reproduction can introduce new gene combinations into a population. This is achieved by formation of gametes by meiosis and then fertilization.
Mitosis does not produce variations.
