Solution

The correct option is D $+ Q$ on the outer surface
We know that charge always resides on the outer surface a of hollow conductor to attain the equilibrium position(at this distance the electroststic repulsion is lowest between charges),Therefore charge $Q$ will be equally distributed on the outer surface of coppr sphere
