Answer: (D)

Verified step by step guidance

1. Understand the concept of cell division: Cell division is a process by which a parent cell divides into two or more daughter cells. It is a fundamental part of the life cycle of many organisms, allowing for growth, reproduction, and repair.
2. Identify the types of organisms that undergo cell division: Generally, living organisms such as bacteria, fungi, plants, and animals undergo cell division. This process is essential for their survival and propagation.
3. Examine the characteristics of prions: Prions are infectious agents composed of protein. They do not have nucleic acids and do not undergo cell division. Instead, they replicate by inducing abnormal folding of normal cellular proteins.
4. Examine the characteristics of viruses: Viruses are acellular entities that require a host cell to replicate. They do not undergo cell division themselves but instead hijack the host's cellular machinery to produce new virus particles.
5. Examine the characteristics of bacteria and fungi: Bacteria are single-celled organisms that reproduce through binary fission, a form of cell division. Fungi, which can be unicellular or multicellular, also undergo cell division as part of their growth and reproduction processes.
