Explanation:
Option A is correct (Alfred Wallace).
According to the evolution theory all living species are evolved from a simple life source with the passage of time.
Points of natural selection:
- Genetic variation are passed from generation to generation but environment can cause variations too.
- Individuals in species have gene variation which is due to random mutation
- Those who can not adopt to environment can not have their genes pass to next generation.
- Natural Selection is also called as "Survival of the fittest".

Eukaryotic: mitosis: prokaryote: binary fission
Eukaryotic cells reproduce by mitosis while prokaryotes reproduce by binary fission.
Eukaryotes include fungi, plants, and animals and are complex in structure. They have a nucleus, several organelles and more DNA (deoxyribonucleic acid). Eukaryotic cells undergo mitosis; a form of cell division that usually produces two similar daughter cells with the same genetic component as the parent cell. Prokaryotes include bacteria, and archaea, and are quite simple in structure. They do not have organelles or nucleus, but they have only a small amount of DNA. Prokaryotes undergo binary fission; a type of asexual reproduction in which there is replication and segregation of a single DNA molecule.
