C Correct answer
Explanation

Polarized glass is used in sunglasses to reduce glare from reflective surfaces, in camera filters to manage reflections and enhance contrast, but standard mirrors do not use polarized glass. Mirrors work by specular reflection using metallic coatings (silver, aluminum) on glass, which doesn't require polarization. While polarizing mirrors exist for specialized applications, standard mirrors are not polarized.
