Final answer:
An Optical Microscope is the device that uses a condenser to project a concentrated light through the examined object to create an image.
Step-by-step explanation:
The apparatus that uses light, concentrated through a condenser and focused through the object being examined to project an image, is a C. Optical Microscope. In an optical microscope, light is directed from an illuminator at the specimen, and this light is then passed through a condenser lens, which focuses all of the light rays on the specimen to maximize illumination. Some optical microscopes use special illumination techniques like dark field microscopy, where a hollow cone of light is focused on the specimen, creating bright objects on a dark background.
