Option b. is incorrect. Bacteria form endospores when conditions are unfavorable for them. These endospores can survive for years in adverse conditions. Option c. is incorrect. Conjugation is the process by which one bacterium transfers genetic information to another bacterium, thus increasing the genetic diversity of the population. Option d. is incorrect. A mutation is the process by which the genetic material of an organism changes randomly. Option a. is correct. Binary fission is a method of asexual reproduction used by prokaryotes. This does not produce genetic diversity because offspring are all clones of the parent. No new genetic material is introduced.
