During confocal microscopy images are generated by bouncing

During confocal microscopy, images are generated: by bouncing electrons off the surface of the sample from specimens covered in electron-dense heavy metals in a single plane of focus: an optical section by passing a light source through the specimen from unstained, living cells

Solution

Answer : The correct answer is C ( In a single p[lane of focus: an optical section). This microscope is extensively used in the imaging of fixed as well live cells and tissues.
