The b-factories, such as BelleII, BarBar and LHCb, emphasize the increasing importance of exotic hadron research. In this paper, we discuss the possible production of singly anti-charmed pentaquark states cq qqq from B mesons in the b-factory under SU(3) symmetry analysis. Discussions of both possibilities have been driven by the hypothesis that the pentaquark state considered in this work, known as the lowest lying state P c, could be bound or unbound. We find the golden channels for the production of the pentaquark ground states, such as B0 → P_csudu(′) 0Σ0. We further estimate the branching ratios for the production of the ground states P c from B meson decays. Thus, multiple channels are available for experiments, which may remove certain obstacles to the discovery of new pentaquark states.
