Answer:
A regular hexagon has 6 lines of symmetry.
A line of symmetry is a line that divides a shape into two identical halves. In the case of a regular hexagon, there are six lines of symmetry because we can draw six lines that divide the hexagon into two equal halves.
Each line of symmetry passes through the center of the hexagon and intersects opposite sides at a 180-degree angle. This means that when we fold the hexagon along any of these lines of symmetry, the two halves will perfectly overlap.
Therefore, the correct answer is option OB: 6.
