Highest energy will be absorbed to eject out the electron in the
configuration.

View answer and explanation

Correct option: B

1{s^2}2{s^2}2{p^3}

The correct answer is B (

1s^22s^22p^3

) because the half-filled p-orbital configuration provides extra stability, requiring more energy to remove an electron.
