Sexual reproduction is present in higher forms of life and absent in prokaryotes like bacteria. Sexual reproduction results in greater evolutionary changes due to the fusion of two different gametes from two different individuals of a species.
Therefore sexual reproduction helps in increased genetic diversity in higher forms of life. In prokaryotes like bacteria, genetic diversity is maintained and increased through DNA transfer from one bacterial cell to another with the help of a process known as horizontal gene transfer.
Bacteria have sex pilli which is used to introduce the genes to the other bacteria. By this process, they increase their genetic diversity and evolve continuously. So the correct is b. I and II.
