Single Correct Answer Type
If the angles \( A, B \) and \( C \) of a triangle are in an arithmetic progression and if \( a, b \) and \( c \) denote the lengths of the sides opposite to \( A, B \) and \( C \) respectively, then the value of the expression \( \frac{a}{c} \sin 2 C+\frac{c}{a} \sin 2 A \) is
