Explanation:
Detailed explanation-1: -In an optical fibre, the refractive index of the core should be lesser than the refractive index of the cladding.
Detailed explanation-2: -In case of an optical fibre cladding is a rarer medium and core is a denser medium .
Detailed explanation-3: -The refractive index of the core is higher than that of the cladding, so light in the core that strikes the boundary with the cladding at an angle shallower than critical angle will be reflected back into the core by total internal reflection.
