Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason: R 
Assertion A: The nuclear density of nuclides ${ }_5^{10}\mathrm{B},{ }_3^6\mathrm{Li},{ }_{26}^{56}\mathrm{Fe},{ }_{10}^{20}\mathrm{Ne}{\text{ and }}_{83}^{209}\mathrm{Bi}$ can be arranged as ${\mathrm{\rho }}_{\mathrm{Bi}}^{\mathrm{N}}>{\mathrm{\rho }}_{{\mathrm{F}}_{\mathrm{e}}}^{\mathrm{N}}>{\mathrm{\rho }}_{\mathrm{Ne}}^{\mathrm{N}}>{\mathrm{\rho }}_{\mathrm{B}}^{\mathrm{N}}>{\mathrm{\rho }}_{{\mathrm{L}}_{\mathrm{i}}}^{\mathrm{N}}$   
Reason R: The radius R of nucleus is related to its mass number A as R = R₀A^1/3, where R₀ is a constant.
In the light of the above statements, choose the correct answer from the options given below
