Solution

The correct option is D Bacterial cell
The cell observed by Rahul was a bacterial cell.
Bacteria are prokaryotes and hence, do not have a well-defined nucleus. They have a cell wall which provides structural support. The major difference between a prokaryotic and eukaryotic cell is that eukaryotic cells have a well-defined nucleus and membrane-bound organelles. Bacterial cells being prokaryotic, will have a floating nuclear region called the nucleoid.
