The correct answers are:
there must be charges on the surface or inside itself
,
there cannot be any charge in the body of the conductor
there must be charges on the surface or inside itself
,
there cannot be any charge in the body of the conductor
The main concept used are :
1. The charge resides on the outer surface of a closed charged conductor
2. Net charge inside the conductor is zero.
The excess charge can reside only on the surface of conductor and inside net positive and negative charge is zero, so any charge can reside inside the hollow shell or body. So, inside the solid material of conducting body there is no charge, it comes to outer surface.
