1) coordinates of D are (7,3) => BC = 3 = DE; coordinates of E are (4,3) length AB is not known, hence y coordinate of F is not known. Not sufficient.
2) Given C (7,1); BC = 3 = DE F = (4,1) 2 is sufficient.
Option B

How did you get BC= 3 from statement 2?? Sent from my iPhone using GMAT Club Forum mobile app

So, the distance between B and C will be the difference between their x  coordinates = 107 = 3 or if still not clear use the distance formula which is \(sqrt((difference between x coordinate)^2 + ( difference between y cooridante ) ^2 )\). Hence, B is sufficient.

B it is Only B gives the coordinates of ve y axis and a and C points combined together gives the equal distances of x axis .

Not sure if I’m looking at this the right way, but I imagined that I was making right triangles on the diagram. If I know the point C I would know AB and CB because of the change in horizontal/vertical axis. If know that and I know that EF=AB and DE=BC I should be able to find point F. Point D would let me find the horizontal length of the horizontal lines, but I’d have no way of knowing the Y axis changes
