When light is incident on a doubly refracting crystal, two refracted rays-ordinary ray (O-ray) and extra ordinary ray (E-ray) are produced. Then                                                       [KCET 2001]

A)            Both O-ray and E-ray are polarised perpendicular to the plane of incidence

B)            Both O-ray and E-ray are polarised in the plane of incidence

C)            E-ray is polarised perpendicular to the plane of incidence and O-ray in the plane of incidence

D)            E-ray is polarised in the plane of incidence and O-ray perpendicular to the plane of incidence
