In the three-dimensional space, consider a cube Q and a plane p passing through 4 vertices of the cube that do not belong to the same face. If the measure of the edge of the cube is 3, then the intersection between the cube and the plane is:

a) a segment that has length 3
b) a square whose sides have length 3
c) a square whose sides have length √18
d) a rhombus (not a square)
e) a rectangle whose perimeter is 6(1+√2)
