The angle of incidence for maximum polarization by reflection can be found using the Brewster's angle formula, which states that tanθ_p = n2/n1 where θ_p is the Brewster's angle, n1 is the refractive index of the incident medium, and n2 is the refractive index of the reflector medium.

In this case, n1 = 1 (air), n2 = 1.33 (water), so tanθ_p = 1.33/1. Solving for θ_p, we get θ_p = 53º. Therefore, the best choice is B.

The Index of Refraction of Water Is 1
