N has 3 unpaired electrons in its ground-state electron configuration (1s² 2s² 2p³). As has 3 unpaired electrons in its ground-state electron configuration (1s² 2s² 2p⁶ 3s² 3p³). Bi has 3 unpaired electrons in its ground-state electron configuration (1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p³). Therefore, option A is correct.
