Which of the following cubes in the answer figures cannot be made based on the unfolded cube in the question figure?

In an unfolded cube net layout, alternate faces are always opposite to each other when folded into a 3D cube. Two opposite faces can never be seen adjacent to one another on a formed cube.
By evaluating the layout of the unfolded net, determine the opposite face pairs. Look through the options to see if any cube shows two opposite faces touching side-by-side.

Upon testing, the face configurations in option B present a combination where faces that are supposed to be mutually opposite are shown adjacent to each other. Hence, the cube in figure B cannot be formed.
