Choose the incorrect alternative considering the Double-cut-and-Join operation

a) This operation occurs on a set of four vertices initially divided in two pairs.
b) The fist part of DCJ operation is breaking the existing connections between the vertices.
c) The second part of DCJ operation is joining the vertices in a way that each vertex gets connected to another vertex which is different from the one it was previously connected to.
d) There are three different outcome configuration possible after the second part of the DCJ operation since for each considered vertex, there are 3 possible vertices that can be connected to it (and 1 vertex that is discarded - the one which was originally connected to the vertex considered)
e) None of the above
