It has just 2 lines of symmetry, l and m
Some people think that the lines along the diagonals (like n) are also lines of symmetry; but when you reflect along that line n, the image does not fit the outline of the original.

Explanation:
A line of symmetry is a line that divides a shape into two congruent parts that are mirror images of each other.

For a rectangle, we can draw a line of symmetry vertically down the middle, dividing the rectangle into two congruent halves.

However, we can also draw a line of symmetry horizontally across the middle, dividing the rectangle into two congruent halves.

Therefore, a standard piece of paper (which is a rectangle) has two lines of symmetry.

The correct answer is option B.
