We know that C = arc sin (1/u)
where c = critical angle
u = refractive index
when angle of incidence is greater than the critical angle, the light ray grazes along the surface and suffers total internal reflection
so answer is d)
checking the other options, it travels from denser to rarer as the ray is bending away from the normal..
also, glass is denser than water as it floats
so, answers are b,c and d
