Solution
The correct option is B A & B are correct
In double - refraction the refractive index of the extra - ordinary ray varies according to the direction taken because it has components that are both parallel and perpendicular to the crystal's optic axis. Thus (A) is correct.
The ordinary ray and the extraordinary ray are polarized in planes vibrating at right angles to each other. Thus (B) is correct.
