According to the Aufbau principle and the electron configuration rules, the shell with n=2 includes two subshells: the first subshell with l=0 and the second subshell with l=1. The first subshell, also known as the 2s subshell, can have a maximum of 2 electrons, while the second subshell, also known as the 2p subshell, contains three orbitals, each capable of holding up to two electrons, for a total of 6 electrons. Therefore, the 2nd shell has a total of 2+6 = 8 electrons, and 4 orbitals. Therefore, the best choice is B, which states that the 2nd shell contains 2 subshells, 4 orbitals, and up to 8 electrons.
