For a regular hexagon, statement true: angle of rotation is $60^{\circ}$ . Among the choices "(i) order is $4$ , (ii) angle of rotation is $60^{\circ}$ , (iii) all angles are equal", the answer is —

a(i)
b(ii)
c(i) and (iii)
d(i), (ii) and (iii)

ব্যাখ্যা

Only statement (ii) is given as correct: the smallest angle of rotation is $\frac{360^{\circ}}{6}=60^{\circ}$ . Statement (i) is false because a regular hexagon's order of rotational symmetry is $6$ , not $4$ .
