Answer: (A)

Verified step by step guidance

1. Understand the concept of binary fission: Binary fission is a form of asexual reproduction commonly found in prokaryotic organisms such as bacteria.
2. Recognize the key characteristic of binary fission: It involves the division of a single parent cell into two genetically identical daughter cells.
3. Differentiate binary fission from other processes: Unlike mitosis or meiosis, binary fission does not involve the formation of a spindle apparatus or the pairing of homologous chromosomes.
4. Eliminate incorrect options: The process by which one cell splits into four cells is more characteristic of meiosis, and the process by which two cells combine to create a new cell is characteristic of fertilization.
5. Identify the correct definition: The process by which one cell splits into two cells is the best definition of binary fission.
