If the Electric Field Is 12 V/m in the Positive

If the electric field is 12 V/m in the positive x-direction, what is the potential difference between the origin, (0, 0) , and the point (3.0 m, 4.0 m) ?

A) 48 V with the origin at the higher potential
B) 48 V with the origin at the lower potential
C) 36 V with the origin at the lower potential
D) 36 V with the origin at the higher potential
E) cannot be determined
