It will be 20 degree.... Medium A

explain
m sry.. it will be MEDIUM C
we know that the ratio of sine of angle of incidence to the sine of refraction gives refrctive index.increase in refractive index increases the range of bending.here angle of incidence is same in every case.the angle of refraction is greater in c.so,it has less refractive index and hence light suffer less bending,which increases its speed.

where angle of refraction will be least. i.e 20` as refractive index will be less
explain
it is in c as in medium c angle of refraction will be highest and sin i/sin r will be less and hence least refractive index and light will bend least in that case
yes
