Then I thought the answer might be C and G, but that's also incorrect, I'm just not sure what to do!

Extend the mirrors 1, so that you can find a point perpendicularly behind the mirror, and the same distance behind as well - as always happens with a flat mirror.
Now extend mirror 2 and repeat the above step for the final image position.

Perhaps remember that mirrors don't magnify an image so the image can't appear closer than the distance a light ray takes from the object to the eye via the mirrors.

Then I would think B would be the image from 1, but then there is no image from 2... I mean D is perpendicular, but it is further away then the distance from the object to the original mirror

As PeterO says, extend mirror 1 (in this case, up and to the right). If the object is at O and the image is at point X then you should find that the mirror perpendicularly bisects OX. That is not true of OB.heatherro92 said:

You got B by extending the line from the object past the end of the existing mirror 1. That line is not perpendicular to the mirror.
I said extend mirror 1 - especially up to the right - then draw a line from the object that forms a right angle with the mirror.
Images in plane mirrors are DIRECTLY behind the mirror - so the line joining an object and and image is always perpendicular to the mirror.
