  In this paper, we continue the study of some controllability issues for the
forward stochastic parabolic equation with dynamic boundary conditions. The
main novelty in the present paper consists of considering only one control
without extra forces in the noise parts. Utilizing an adequate spectral
inequality and the iterative Lebeau-Robiano strategy, we first establish an
observability inequality for the corresponding adjoint backward stochastic
system. The null controllability result is then established by the classical
duality approach. As a consequence of the null controllability property, an
approximate controllability result is proved.
