Hint- We will find out the number of lines that can be drawn across the rectangle such that we obtain an exact mirror image every time with the help of a figure.

Complete step-by-step answer:

$ \Rightarrow $ There are $2$ lines of symmetry of a rectangle which are from the midpoints of the length and the breadth of the rectangle.

$ \Rightarrow $ These are two lines as shown in the figure that cut the rectangle in two similar halves which are mirror images of each other. If a rectangle is folded along its line of symmetry, it superimposes perfectly.

Hence, Rectangle has $2$ lines of symmetry.

So, option B is the correct option.

Note- Line of symmetry of any figure is drawn by the use of figure. We say there is symmetry when the exact reflection or mirror image of a line, shape or object gets created. The line of symmetry can be defined as the axis or imaginary line that passes through the center of the shape or object and divides it into identical halves.
