Detailed Solution

Concept- If a central dividing line (also known as a mirror line) can be drawn on a form to demonstrate that both of its sides are identical, then the shape exhibits symmetry. We will thus use this approach to verify each provided line one at a time.
The line that runs through the middle of an item or any form is known as the line of symmetry. It is referred to as the object's axis or imaginary line. We must have studied symmetry in great detail in geometry. Symmetry is described as a balanced and proportionate likeness between two halves of an item, where one half is the mirror image of the other.
Alternatively, we may say that the term "line of symmetry" refers to the fictitious axis or line that allows us to fold a figure into symmetrical halves. The axis of symmetry is another name for it. Due to the fact that it displays two coincident reflections of the same picture, the line symmetry is also known as a mirror line. As a result, it is a kind of reflection symmetry as well. In essence, it splits one thing into two pieces. There can be 1 or more than 1 symmetry lines.
Given lines are L, M, and N; if we look at line L, there is no symmetry or mirror image; similarly, if we look at lines M and N, neither of them can create a mirror image.
Hence, the correct answer is option 4.
