(C) The ionic radius ratio $\left( \frac{r_c}{r_a} \right)$ determines the coordination number and geometry of the crystal lattice.For a radius ratio in the range $0.414 - 0.732$,the coordination number is $6$,which corresponds to an octahedral geometry.Since the given value $0.52$ falls within this range,the geometrical arrangement is octahedral.
