Answer:
A.
Explanation:
We have been given an image. We are asked to find the line of symmetry for our given image.
We can see that our given image is symmetric about y-axis as y axis divides our given image into two mirror images.
We also know that at y-axis the values of x is always 0, therefore, the line
represents line of the symmetry for the given figure and option A is the correct choice.
