Answer:
The correct answer is 619.
Step-by-step explanation:
A number is said to have point symmetry when turning it upside down, that is, turning it 180º, remains the same.
As for geometric figures, the same thing happens. It is symmetrically the same if it is built around a center and when turning it does not change its shape.
That is why the correct option is 619 (6I9).
