D Correct answer
Explanation

A polarizer selectively transmits light waves oscillating in a specific direction while blocking others. When randomly polarized light (which contains waves vibrating in all directions perpendicular to propagation) passes through a linear polarizer, only the component aligned with the polarizer's transmission axis passes through. The emerging light becomes plane-polarized, meaning all waves vibrate in the same direction. It is not partially polarized (which implies some randomness remains), blocked (which would mean no transmission), or unchanged.
