It is "find the next box matching the trend" sort of thing. The question as given is:
I need to fill the blank area with the correct box given from 6 options:
What I get from the question is that there is an color inverse of every box given, i.e. for every box in this collection, there is another box of the same pattern but which is negative of that box. But only for the black box there is no negative. So it implies that the answer should be white one(Option 1). However the thing that confuses me is that why are there two black boxes? Please solve this puzzle and state if my reasoning is correct or not. Thanks in advance.
