A ray of light moving along a vector `(3sqrt(2) hat(i)-3 hat(j)-3 hat(k))` undergoes refraction at an interface of two media which is y-z plane. The refractive index for `x le 0` is 1 while for `x ge 0` it is `sqrt(2)`. Then,
A. Refracted ray bend towards y-axis
B. Refracted ray bend towards x-axis
C. The unit vector along the refracted ray is `(sqrt(3)hat(i)-hat(j)-hat(k))/(2)`
D. The unit vector along the refracted ray is `(sqrt(6)hat(i)-hat(j)-hat(k))/(sqrt(8))`
