Detailed Solution

Concept- A line of symmetry is a line that divides an image into two mirror images. It can be vertical, horizontal, or diagonal. The image can also contain multiple lines of symmetry.
A line of symmetry is an imaginary line or axis along which a folded figure produces symmetrical or identical halves. These halves are mirror images of each other. You need to find the number of letters with at least one line of symmetry. So
The letter O is in the shape of a circle. In a circle, all straight lines passing through the center of the circle are lines of symmetry. A circle has infinite lines of symmetry. Letters L and P do not have lines of symmetry. This is because lines do not divide a letter into two mirror images, vertical, diagonal, or horizontal. The letters Y, M, I, and A have vertical lines of symmetry. There is a horizontal line of symmetry in the letter D.
Hence, option 4 is correct.
