One day I got a paper from my courtyard with the center portion missing. Here is what the poster looks like:

pattern with center portion missing

I have made some pieces of paper so that I can stick one to the center of the poster.

Here are the pieces.

pieces that would fit the missing center

Help me find the best one that will suit the poster. Also, let me know why it will be the best. I will approve the answer with most appropriate justification.

    $\begingroup$ Isn't it trivial to see the solution even without the five suggestions, or is something wrong with my eyes? :) $\endgroup$

I think you should go with number 3 because it almost matches the pattern in the original paper. However, other options also look reasonable.

Edited: It depends on what you see at the "pattern" in the original diagram. Not everyone sees W, X, Y, and Z as the pattern in the given figure. There is an unique pattern by using number 3 and it looks cool.

  • $\begingroup$ Welcome to Puzzling Stack Exchange! Would it be possible to edit your answer to expand upon why you believe(d) #3 is the correct answer? Thank you! $\endgroup$
