In an experiment where a ray of light is directed from air into water, if the angle of incidence is 46 degrees, choose 1 option which gives the angle of refraction predicted by Snell's law, correct to 2 significant figures, given that n = 1.208.

A) 0.84 degrees

B) 0.85 degrees

C) 23 degrees

D) 36 degrees

E) 37 degrees

F) 45 degrees

G) 46 degrees

H) 47 degrees
