Solution

The correct option is A If both assertion and reason are true and reason is the correct explanation of assertion.
The sound wave cannot be polarized, because sound wave is longitudinal, meaning they oscillate parallel to the direction of motion. Since there is no component of sound which is perpendicular to the direction of motion, so sound waves can not be polarised.
Both assertion and reason are true and the reason is the correct explanation of assertion.
