John’s clock is broken. The minute hand rotates around the clock correctly, but the hour hand is stuck in the three o’clock position.

Through which of the following could the minute hand have rotated to reach its current position?

Wow I just completely over thought it. ._. Alright, so there is this thing in math (I'm forgetting what it's called) that basically says if you add or subtract 360 (a full circle) you'd wind up at the same place that you started. So if you started at -135 and subtracted 360, what would you get?
