The information from one place to another can be transmitted very safely and easily by:

Explanation

Optical fiber is a technology that allows the transmission of information from one place to another using light signals. An optical fiber is a thin, flexible, and transparent fiber made of glass or plastic that can carry light signals over long distances with minimal loss of signal.The principle of optical fiber communication is based on the phenomenon of total internal reflection, where light traveling through a medium with a higher refractive index is reflected when it encounters a medium with a lower refractive index at an angle greater than the critical angle.Compared to Copper wire or Aluminium wire, optical fiber has several advantages, including higher bandwidth, lower attenuation, greater immunity to electromagnetic interference, and greater security since it is difficult to tap into the signal without breaking the fiber.Therefore, the correct option is Optical fiber.
