(C) For a compound with $NaCl$ structure, the limiting radius ratio is $0.414$.The radius ratio formula is given by $\frac{r^+}{r^-} = 0.414$.Given that the radius of the cation $r^+ = 100 \ pm$, we substitute this into the equation:$\frac{100}{r^-} = 0.414$$r^- = \frac{100}{0.414} \approx 241.54 \ pm$.Rounding to the nearest option, the radius of the anion is $241.5 \ pm$.
