H-polaroid is prepared by

View answer and explanation

Correct option: D

Stretching polyvinyl alcohol and then impregnation with iodine

Option D (Stretching polyvinyl alcohol and then impregnation with iodine) is correct because H-polaroids are manufactured by stretching polyvinyl alcohol films and then impregnating them with iodine, which aligns the polymer chains and creates a polarizing effect.
