Answer: The image after reflection is shown in below figure.
Step-by-step explanation:
From the given figure it is noticed that both the lines l and m are vertical lines.
The alphabet D has two sides one is straight side and another one is a curve.
The distance between straight side of D is more the distance between curved side. Therefore once we reflect the D we get the mirror image of D across the line l.
It means after reflection the distance between straight side of D is more the distance between curved side but the image is in the opposite side of the line l.
After That the we reflect the resultant image across the line m ge get the same the alphabet as the resulted image.
