Solution

The correct option is A Only A is correct
Most of the cells are microscopic in size. Hence, they are not visible to the naked eye. They need to be enlarged or magnified by a microscope to be seen. E.g., the bacterial cell (0.1 to 0.5 mm). On the other hand there are certain cells, like the egg of a hen, which can be seen with the unaided eye.
