Solution:Concept- Apply the fact that an n-sided regular polygon's rotational symmetry order is always equal to n.
The figure is given as
Let us just examine rotational symmetry in order to explain this question.
When an object is rotated (turned) a certain number of degrees about its center, it is said to have rotational symmetry.
The number of positions an object appears the same in a 360o rotation is the order of symmetry.
For the given figures, there are 5 rotational symmetry orders.
Hence, the correct answer is option (4).
