Solution
The correct option is A Total internal reflection
An optical fiber is a cylindrical dielectric waveguide(nonconducting waveguide) that transmits light along its axis, by the process of total internal reflection. The fiber consists of a core surrounded by a cladding layer, both of which are made of dielectric materials. To confine the optical signal in the core, the refractive index of the core must be greater than that of the cladding. The boundary between the core and cladding may either be abrupt, in step-index-fibre, or gradual, in graded-index fibre.
