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.
