Solution

The correct option is A
Vertical plane

When unpolarized light is made to incident at the polarising angle, the reflected light is plane polarised in a direction perpendicular to the plane of incidence.
Therefore the electric field in reflected light will vibrate in vertical plane with respect to plane of incidence.
