Figure 1 represents antimony whose electronic configuration is represented in the form of graph :
1s2 - 2s2 2p6 -3s2 3p6 3d10 - 4s2 4p6 4d10 - 5s2 5p3 is the representation of above graph of number of electrons and energy in Mj/mol.
This can be also written as : [Kr] 4d10 5s2 5p3 where Krypton electron configuration is 1s2 2s2 2p6 3s2 3p6 3d104s2 4p6 .
Hence correct option is first option where antimony(Sb) electron configuration is written in the format of electronic orbital diagram where Krypton is in inner core, outermost third orbital layer contain 3 electrons ( 5p3), next inner second orbital layer contain 2 electrons (5s2) and innermost first layer contain 10 electrons (4d10).
