Answer:
a.It has both line symmetry and rotational symmetry.
Step-by-step explanation:
The line symmetry is another name for reflection symmetry, where if you fold the image to get two half figures, both the halves will be exactly same. First half is the reflection of the other half.
A shape is said to have rotational symmetry, when it looks the same after being rotated.
The given figure has both symmetries.
So, the correct answer for given figure is - It has both line symmetry and rotational symmetry.
