Light is reflected off the rear windshield of a car, as in the last question. At what position of the polarizer is the transmitted intensity at a minimum, and why?

At all positions, the intensity will be minimum because light transmits through two surfaces.

$0$ and $180,$ because light reflected from the windshield is parallel with the Polaroid axis.

$0$ and $180,$ because the polarization of the reflected light is crossed with the Polaroid axis.

$90$ and $270,$ because the polarizations of the plane waves are perpendicular to the axis of the Polaroid.

$90$ and $270,$ because the polarization of the reflected light is parallel with the axis of the Polaroid.
