The line of symmetry is the line about which either part of the image will coincide with the other thus option (B) shows the line of symmetry.
What is symmetry?
If two figures look an exact shape but their size could be small or big then both figures are called similar figures.
When anything has identical pieces facing one another or revolving around an axis, it is said to be symmetrical.
The line of symmetry is the line about which either part of the image will coincide with the other.
For example, a square is symmetric about its diagonal if we flip one part of the square on either side of a square with another side then they will completely coincide with each other.
In the second image if we flip the left part to the line of symmetry to the right then it will coincide with the right part of the image.
Hence "The second image shows is the symmetric about the line of symmetry".
