(i) The inner surfaces of `B`and `C` will have the same charge
(ii) The inner surfaces of `B` and `C` will have the same charge density
(iii) The outer surfaces of `A,B` and `C` will have the same charge
(iv) The outer surfaces of `A,B` and `C` will have the same charge density

Options

A. `(i),(ii)`
B. `(ii),(iii)`
C. `(ii),(iv)`
D. `(i),(iii)`

Answer
