Light passes through two different polarizers. The first is aligned vertically, while the second is aligned horizontally. How much light makes it through the two polarizers?

These are the options from the practice homework in book. I'm confused bc they're not alligning. Any insight? Thanks.
-None of it. This first only lets vertically polarized light through. the second only let horizontally polarized light through.
-All of it. Since the two polarizers aren't aligned with each other, they don't affect the light.
-One quarter. Each polarizer reduces the light by half. Half of half is one quarter.
-70.7%. The combination of the two polarizers (one at 0 and the other at 90) is 45. Cos(45)=.707.
