Which of the following electronic configuration represent a violation of Hund's rule for an atom in its ground state?

Solution
The correct option is A
According to Hund's rule:
- Every orbital should be singly occupied before any orbital is doubly occupied.
- All of the electrons in singly occupied orbitals should have the same spin (to maximize total spin).
Among the given options the configuration in which two electrons got paired first rather than filling all remaining orbital with one electron is violating the Hund's rule.
