Please answer the following question...
Dear Student
As ray bends towards normal when passes from medium A to B.
Hence medium A is rarer than medium B. Medium B is denser.
Means the refractive index of medium B is more than that of A.
So refractive index of medium B relative to medium A greater than unity.
