Given vectors M and N in the figure below, which of the following is most likely the correct diagram for the vector difference M - N?

A red vector pointing downwards in a coordinate system, representing a possible vector difference.

A red vector pointing horizontally to the left in a coordinate system, representing a possible vector difference.

A red vector pointing diagonally downwards to the left in a coordinate system, representing a possible vector difference.

A red vector pointing diagonally upwards to the right in a coordinate system, representing a possible vector difference.
