(D) According to the shell theorem and the properties of conductors in electrostatic equilibrium,the electric field inside a uniformly charged spherical shell is zero. Even if the shell is not uniformly charged due to the presence of an external charge $q'$,the charge $Q$ on the shell will redistribute itself such that the electric field produced by the shell at any point inside it is zero. Since the electric field due to the shell at the center is zero,the force exerted by the shell on the central charge $q$ is $F = qE = q(0) = 0$.
