Umm...there's no way that's C.

I'd say A or D.

Is this Crack DAT PAT?

It looks like D to me. A is too small.

A is too small, D cannot work because it is too thin. If you look at the figure,the choice D is as thick as one of the flaps on the figure. The hole must account for the hexagonal plate's width as well. C is the only one that works. If you pass the item through the direction that I drew on the attachment.

If you have hard time seeing it, let me know.
