Answer: D
QIH = QRS
Q = Q
I = R
H = S
We are looking for a diagram that states QI = QR and IH = RS in that exact order, with the correct congruency marks. QR corresponds to QI with one congruency mark, IH corresponds to RS with two congruency marks. Now, all you need to do is find a triangle that has the congruency marks in the correct order.
Diagram D fits this criteria.
