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 ₅¹⁰ ~B, ₃⁶ Li, ₂₆⁵⁶ Fe, ₁₀²⁰ Ne and ₈₃²⁰⁹ Bi can be arranged as ρ Bi ^(N)>ρ Fe ^(N)>ρ Ne ^(N)>ρ B ^(N)>ρ Li ^(N) Reason R: The radius R of nucleus is related to its mass number A as R=R₀ A^(1 / 3), where R₀ is a constant. In the light of the above statements, choose the correct answer from the options given below

(A) Both ~A and R are true and R is the correct explanation of A

(B) Both A and R are true but R is NOT the correct explanation of A
