Response:Given Right Δ DEF,Which is not a given that if ∠D=∠F =90°As a look at the options that it offers , Either of the Base and height =3 or 4 and the Hypotenuse =5, the Case 1. When ∠D=90°In Δ And D FSin (E) = = 3/5 Or 4/5 [ if base=3, altitude =4, and if the Base =4, Height=3]Case 2. When ∠F=90°, In ΔEFD Sin (E) = = 3/5 or 4/5 [Depending on if Base =3 then height =4, Or the Altitude =3 , then the Base =4]So looking at all the options of 3/5 and 4/5 are the correct answers.But given that the answer is 3/5 , so if you take ∠D or ∠F 90° take Altitude=3 and the Hypotenuse =5 and base =4.
