If AB=DEAB = DE, AC=DFAC = DF, ∠A=∠D=90∘\angle A = \angle D = 90^\circ and BC=5BC = 5 cm, then EFEF is equal to _______. ![Two right-angled triangles, Triangle ABC and Triangle DEF. Both have the right angle at A and D respectively. Side AB is marked with one tick, and side AC is marked with two ticks. Side DE is marked with one tick, and side DF is marked with two ticks. This indicates that AB corresponds to DE and AC corresponds to DF.](https://storage.googleapis.com/diraq-contents/homework-question-parsing/marker/20260106T182719Z/2f80bdec1578447c90c0cf5414bb53de/935eed7aa61f7777f62cfc032e11bee9_img.jpg) (A) 5 cm (B) 4.5 cm (C) 5.5 cm (D) Can't be determined
