The correct answer is C. In a compound microscope, light typically passes through the following sequence of components: The light source (often directed by a mirror or built-in lamp) illuminates the specimen, usually passing through a condenser which focuses the light onto the specimen. The light then passes through the specimen, enters the objective lens (which forms a magnified real image), travels up the body tube, and finally passes through the eyepiece (which magnifies the real image to form a virtual image viewed by the observer’s eye).

The correct sequence for light passage in a compound microscope is typically Condenser -> Specimen -> Objective lens -> Body tube -> Eyepiece.

The condenser is located below the stage and its function is to focus the light onto the specimen to provide optimal illumination. The objective lens is located above the specimen and is the primary magnification component. The body tube connects the objective lens to the eyepiece, and the eyepiece is where the user looks to view the final magnified image.
