(a) The given figure has its rotational symmetry as 4.
(b) The given figure has its rotational symmetry as 3.
(c) The given figure has its rotational symmetry as 1.
(d) The given figure has its rotational symmetry as 2.
(e) The given figure has its rotational symmetry as 3.
(f) The given figure has its rotational symmetry as 4.
Hence, figures (a), (b), (d), (e), and (f) have rotational symmetry of order more than 1.
