For states with larger values of n that admit a d subshell, the d subshell is at even higher energy than the p subshell. In fact, its energy is higher than that of the s subshell for the n+1 state. With this in mind, which of the following are valid ground-state electron structures?1. 1s2 2s2 2p63 s2 3p6 3d22. 1s2 2s2 2p6 3s2 3p6 3d113. 1s2 2s2 2p6 3s2 3p6 4s2 3d5A. 1B. 2C. 3D. 1 and 2E. 1 and 3F. 2 and 3
