A vector in a given plane can have any direction
In XY plane we can say that its direction is
North = + Y direction
South = - Y direction
East = + X direction
West = - X direction
so all of the above directions can be considered as direction of a given vector as a vector can incline in all above direction as well and at any angle with all also
so here it is also possible to have a direction which is along 45 degree North of East which will incline between X and Y direction both
So here all four options may be the possible direction of a vector
