Solution
The correct option is D

Kaleidoscope uses the concept of multiple reflections to get such beautiful patterns. A kaleidoscope contains several mirrors placed at an angle to each other, usually three plane mirrors placed at 60 degrees with each other. This creates multiple reflections of the objects inside the kaleidoscope.
