There are three elements A, B and C. their atomic number are `Z_(1), Z_(2)` and `Z_(3)` respectively. If `Z_(1)-Z_(2)=2 and (Z_(1)+Z_(2))/(2)=Z_(3)-2` and the electronic configuration of element A is `[Ar]3d^(6)4s^(2)`, then correct order of magnetic momentum is/are:

Options

A. `B^(+) gt A^(2+) gt C^(2+)`
B. `A^(3+) gt B^(2+) gt C`
C. `B gt A gt C^(2+)`
D. `B=A^(3+) gt C^(3+)`

Answer

A, B, C
