Solution

The correct option is C A periscope
A periscope works using the principle of the reflection of light between two plane mirrors that are arranged parallel to one another. It is an optical device. Light from an object incidence on the mirror is reflected to the mirror that is parallel to the previous mirror. The reflection from the latter is reflected to the eye of the observer. This device is used to view objects that are not at an eyesight level. This device is mainly used in submarines and in army bunkers.
