Identify the rotational and reflective symmetries of each figure.

$A regular hexagon with vertices labeled 1 through 6 and center marked.$

A regular hexagon is centered at the origin. Which list shows all distinct rotational symmetry angles (in degrees, greater than $0^\circ$ and less than $360^\circ$ )?

$60^\circ$ only

$60^\circ$ , $120^\circ$ , $180^\circ$ , $240^\circ$ , $300^\circ$ , $360^\circ$

$60^\circ$ , $120^\circ$ , $180^\circ$ , $240^\circ$ , $300^\circ$

$90^\circ$ , $180^\circ$ , $270^\circ$
