The correct answer is C. Kaleidoscope.
A kaleidoscope is an optical instrument with two mirrors set at an angle to each other, so that when light is shone through them, it creates an ever-changing pattern of colored shapes. The word “kaleidoscope” comes from the Greek words kalos, meaning “beautiful,” and eidos, meaning “form.”
The first kaleidoscope was invented in 1816 by David Brewster, a Scottish physicist and inventor. Brewster was inspired by the patterns he saw when he looked through a piece of broken glass. He created the kaleidoscope to capture and magnify these patterns, and he soon found that it was a popular toy and novelty item.
Kaleidoscopes are still popular today, and they are often used as gifts or decorations. They can also be used for educational purposes, such as teaching children about symmetry and patterns.
The other options are incorrect because they are not the correct spelling of the word “kaleidoscope.”
