Text Solution

Verified by Experts

The correct Answer is:
C
In .S. atom,
G.S. = no. of unpaired `e^(-)=2`
`(E.S)_(I)=` no. of unpaired `e^(-)=4`
`(E.S)_(II) =` no. of unpaired `e^(-)=6`
In .T. atom
G.S. = no. of unpaired `e^(-)= 1`
`(E.S)_(I)=` no. of unpaired `e^(-)=3`
`(E.S)_(II) =` no. of unpaired `e^(-) =5 `
`(E.S)_(III)=` no. of unpaired `e^(-)=7`
