It's E, just look at the triangles as "flaps" and using the pattern from
>>11342763 and you can see that the triangles with stripes hide the clear ones.
For example on the pattern through the middle, the red one, they invert the position of the traingle on the left and then invert the position of the traingle on the right
The answer is E on the blue pattern because on the image on first row to the image on the second row they invert the position of the right striped triangle so that it is on top of the clear triangle below it and then they would invert the position of the clear triangle on the left, which would be E
