Answer:
Option D.
LA Theorem or Postulates
Explanation:
LA theorem or postulates is leg-acute states that if the leg and an acute angle of one right triangle are congruent to the corresponding leg and acute angle of another right triangle, then the triangles are congruent.
In
and 
[Given]
[Acute angle] [Given]
[Given]
By LA theorems or postulates,

Therefore, LA theorems or postulates support the conclusion that the triangles are congruent.
