Which one of the following is the correct sequence of passage of light in a compound microscope?

In a compound microscope, light follows a specific optical path to achieve magnification. The process begins with a light source or mirror that directs light toward the condenser. The condenser lens focuses this light onto the specimen. After passing through the specimen, the light enters the objective lens, which creates a magnified primary image. This light then travels through the body tube (or eyepiece tube), which maintains the necessary distance between the lenses and holds the optical components in place. Finally, the light reaches the eyepiece (ocular lens), which further magnifies the image for the viewer. Therefore, the correct sequence is Condenser - Objective lens - Body tube - Eyepiece, as it accurately reflects the progression from the illumination system through the primary and secondary magnification stages.
