>>10967219E, because when you look at it in columns, you can see that one is full striped, another one is half-striped above the line and the last one must be half-striped only on one side (left or right).
So, let's say the top-left is #1, top-middle is #2, top-right #3, middle-left, #4, etc.
#1, #4 and #7 are connected;
#2, #5, #8 are connected and
#3, #6 and #9 are connected.
Thus, #1 is half-striped (top, bottom);
#4 is half-striped (left, right);
#7 is full striped;
Then, #2 is half-striped (top, bottom);
#4 is full striped;
#8 is half-striped (left, right);
Finally, #3 is full-striped;
#6 is half-striped (left, right);
#9 must be half-striped (top, bottom);
The answer is E.
