Which of these triangle pairs can be mapped to each other using two reflections?

A
Triangles X Y Z and P Y T are connected at point Y. Triangle X Y Z is reflected across X Y and then is reflected another time across Y Z to form triangle P Y T.
Option A
B
Triangles X Y Z and A Y T are connected at point Y. Triangle X Y Z is reflected 3 times to form triangle A Y T.
Option B
C
Triangles X Y Z and A Y T are connected at point Y. Triangle X Y Z is reflected across side X Y and then is shifted down to form triangle A Y T.
Option C
D
Triangles X Y Z and A Z T are connected at point Z. Triangle X Y Z is reflected and then rotated to form triangle A Z T.
Option D

If A ≅ T, then the triangles would be congruent by ASA.
Option A
B
If B ≅ P, then the triangles would be congruent by AAS.
Option B
C
If all the angles are acute, then the triangles would be congruent.
D
If C and Q are right angles, then triangles would be congruent.
Option D
E
If BC ≅ PQ, then the triangles would be congruent by ASA.
