`A,B` and `C` are three concentric metallic shells . Shell `A` is the innermost and shell `C` is the outermost. `A` is given some charge
(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. Inner surfaces of `B` and `C` will have same charge.
B. Inner surfaces of `B` and `C` will have same charge density.
C. Outer surfaces of `A`, `B` and `C` will have same charge.
D. Outer surfaces of `A`, `B` and `C` will have same charge density.

Explanation

Take Gaussian surface into the metal.
