This is the basic princile because as wave travels from from optically denser medium to optically rarer medium then it moves away from normal so in that case if we want total internal reflection for critical angle to come in action core should have high refractive index.

Optical communication works on the principle of Total Internal Reflection (TIR). For this, to happen the refractive index of the core should be more than cladding material.

According to me, the question should be an optical fiber.
