Stuck on these Pattern Folding Problems

Hey guys,

I was wondering if anyone had a strategy for these kind of pattern folds? I do fine with the rest, but whenever I get these I find it to be extremely time consuming trying to rotate the figure in my head. Has anyone found a way to do these specific pattern folding problems quickly?

Sometimes there's no way around mentally folding/rotating. A can be easily eliminated by observing the orientation of the square piece against the adjacent side, but the rest of the patterns are too similar to allow for easy comparison of just two sides. I think the answer is D, right?

Yeah, it was D. Every once in a while I get one of these and find it time constraining to mentally rotate.
