Sterilization means killing of:
- A. Virus
- B. Fungi
- C. Bacteria
- D. Virus, fungi, bacteria, bacteria spores***
- E. Virus, fungi, bacteria.
The most accurate answer is D. Virus, fungi, bacteria, and bacterial spores.
Sterilization is a process that eliminates all forms of life, including:
- Viruses: Microscopic infectious agents that lack cellular structures.
- Fungi: Eukaryotic organisms that can be single-celled or multicellular, like molds and yeasts.
- Bacteria: Single-celled prokaryotic organisms that can be beneficial or harmful.
- Bacterial spores: Dormant, resistant forms of bacteria that can withstand harsh environmental conditions.
Therefore, to effectively sterilize something, you need to eliminate all of these forms of life, not just a specific type.
Other Options:
The other options are partially correct, but they miss some important elements:
A. Virus:
While viruses are included in sterilization, it doesn't encompass the full range of organisms eliminated by the process.
B. Fungi:
Similar to option A, fungi are included, but sterilization goes beyond just them.
C. Bacteria:
This option misses out on viruses, fungi, and bacterial spores, which are also crucial components of sterilization.
E. Virus, fungi, bacteria:
This option comes close, but it doesn't include bacterial spores, which are highly resistant and require specific sterilization methods.
Remember, sterilization is a critical process in various fields, including healthcare, food safety, and scientific research. It ensures that harmful microorganisms are eliminated, preventing the spread of disease and contamination.
