Figure shows two hollow charged conductors A and B having same positive surface charge densities. \( \mathrm{B} \) is placed inside \( \mathrm{A} \) and does not touches it. On connecting them with a conductor
(a) charge will flow from \( A \) to \( B \)
(b) charge will flow from \( \mathrm{B} \) to \( \mathrm{A} \)
(c) charge oscillates between A and B
(d) No charge will flow.
