folding and unfolding

 A paper sheet in the shape of square is folding as shown in the sketch. After folding two protruding corners are cut and remove as shown in the sketch(shaded portion). after cutting that portion unfold the paper. what shape you will get? choose the correct shape.

don't use a paper for solving this problem. first you try to visualize the folding and unfolding, then try to find out the answer, if you want to boost your creativity.  if you cannot find out the true shape, nothing to worry. use a paper to find out the true shape.
