The correct answer is: $(\mathrm{A})-(\mathrm{R}) ;(\mathrm{B})-(\mathrm{P}) ;(\mathrm{C})-(\mathrm{S}) ;(\mathrm{D})-(\mathrm{Q})$
Relationship between radius of gyration and the moment of inertia about an axis is as follows:
$\mathrm{I}=\mathrm{mk}^2$
Summary for the different cases is listed below:
