Answer:
Option D.
Step-by-step explanation:
A triangle when reflected over x-axis option C is the reflection with a new base of the triangle is at y = -1 and the original picture is rotated 180° over x axis.
Further triangle in option C is reflected through y-axis or rotated at 180° by y axis then the new image will be as option D which is congruent to the triangle in original figure.
Therefore Option D is the correct answer.
