The correct order from smallest to largest is virus, PPLO (Mycoplasma), typical bacteria, and typical eukaryotic cell. Viruses are the smallest, usually only visible with an electron microscope. PPLOs are slightly larger than the largest viruses but smaller than typical bacteria. Typical bacteria are larger than viruses and PPLOs and are visible under light microscopes. Eukaryotic cells are the largest, significantly bigger than viruses, PPLOs, and typical bacteria, making Option A the correct choice.

Understanding the Sizes of Microorganisms
To comprehend the correct arrangement of microorganisms based on size, let's explore each component:
1. Virus
- Viruses are among the smallest biological entities.
- Their size typically ranges from 20 nm to 300 nm.
2. PPLO (Pleuropneumonia-like Organisms)
- Also known as mycoplasmas, they are larger than viruses.
- Their size usually ranges from 0.2 µm to 0.3 µm.
3. Typical Bacteria
- Bacteria are significantly larger than both viruses and PPLO.
- The average size of bacteria ranges from 1 µm to 10 µm.
4. Typical Eukaryotic Cell
- Eukaryotic cells, such as those found in plants and animals, are the largest among these entities.
- Their sizes generally range from 10 µm to 100 µm or more, depending on the type of cell.
Conclusion
Based on the size comparisons:
- Virus < pplo="" />< typical="" bacteria="" />< typical="" eukaryotic="" />
This aligns perfectly with option 'A' from the original question. Each category represents a distinct level of complexity and size, with viruses being the smallest and typical eukaryotic cells being the largest. Understanding these differences is crucial for studies in microbiology and cellular biology, especially for competitive exams like NEET.
