B. 125°
Since angle BFE is 35 degrees and it is a right angle, angle EFD is 90 degrees. Therefore, angle BFD is 90 + 35 = 125 degrees. Since line B-D and E-C intersect at point F, angle BFD is equal to angle DFC. Therefore, the measure of angle DFC is 125 degrees.
The figure below shows ray
and two lines that intersect at point F.
Lines B-D and E-C intersect at F. The angle E-F-B divided into a right-angle and 35 degrees.
