Haha....this one is funny. C and D are both correct, but so is A and B. They are all correct. If you dont beleive me cut it out for yourself.
Think about it. Just listen. B is correct just by looking at the top figure. The top of the box is white. The strip down the center is white and corresponds to the far left strip on choice B. The strip directly to its right is white and corresponds to the middle strip on choice B. The strip to that strip's right is yellow(that's the one that is pointing upward) corresponds to the far right strip on choice B, hence B is a correct choice. Now that I've proved that is possible, it should reveal that all of the figures are possible. This is just a poorly made problem.
*Remember that once an object is folded, it can be rotated in any direction to get your answer. I think many of you guys are forgetting that.
Cut it out for youself and remember to fold into the computer screen. Haha, that was fun. I love pattern folding.
