The correct answer is: A. Its cable looks like a tail.
The computer mouse was invented in 1964 by Douglas Engelbart at the Stanford Research Institute. It was originally called the “X-Y position indicator for a display system”. However, Engelbart’s colleague Bill English suggested that it be called a “mouse” because the cord resembled a tail and the device could be moved around on a flat surface.
Option B is incorrect because the computer mouse does not squeak when moved. Option C is incorrect because the computer mouse does not have ears. Option D is incorrect because the computer mouse does not have teeth outside its mouth.
