Answer
A square has 4 lines of symmetry: 2 joining the midpoints of opposite sides and 2 along the diagonals.
A rectangle has 2 lines of symmetry, i.e., the lines joining the midpoints of opposite sides.
Since 4 is not equal to 2, they have an unequal number of lines of symmetry.
∴ Option 4 is the correct option.
