Which is not a congruence statement based on this pair of polygons

Since this is the same question as you have posted before ill go into deeper explanation to further help you.

Both Triangles are congruent, we know this because all the angles are equal to one another. The missing angle in both triangles is 90 degrees, we know this because these are considered right triangles hence the square in the corner. Looking further into the diagram we notice that B=E, F=A, and D=C knowing this we can then go through the process of elimination.

Answer choice D states A=F, since we already found that F does indeed equal A this statement is true therefore its not the answer.

Answer Choice C states ABC=FED this is asking if angle B is equal to angle E which we already found out to be true so this one is incorrect.

Answer Choice B states the line AC=FD since we know these triangles are congruent we know this statement is true, so this answer is also incorrect.

Answer Choice A states B=D this is false since we allready know B=E not D so this is the correct answer.
