Ans: D
I has rotational symmetry and reflectional symmetry. The centre of the rotation is the intersection of the diagonals. And it is a $2$-fold rotational symmetry figure. Furthermore, there are two axes of reflectional symmetry. One joins the two mid-points of the widths and the other joins the mi-points of the lengths.

II has rotational symmetry and reflectional symmetry. The centre of the rotation is the intersection of the diagonals. And it is a $4$-fold rotational symmetry figure. Furthermore, there are four axes of reflectional symmetry. The diagonals are two of them.
III has rotational symmetry and reflectional symmetry. The centre of the rotation is the intersection of the diagonals. And it is a $2$-fold rotational symmetry figure. Furthermore, there are two axes of reflectional symmetry. They are the two diagonals.
