Solution

The correct option is A $360^{\circ}$
In a complete turn of $360^{\circ}$ , the number of times an object looks exactly the same is called the order of rotational symmetry.
For example: A rectangle has an order of rotational symmetry of 2 since it looks exactly the same at 180° and 360° rotations.
