(C) $Pauli's$ exclusion principle states that no two electrons in an atom can have the same set of four quantum numbers. This means an orbital can hold a maximum of two electrons with opposite spins. $Hund's$ rule of maximum multiplicity states that electron pairing in $p, d,$ and $f$ orbitals cannot occur until each orbital of a given subshell contains one electron each (singly occupied). In option $C$,the first orbital of the $p$-subshell contains two electrons with the same spin,which violates $Pauli's$ exclusion principle. Furthermore,the second orbital is empty while the first is paired,which violates $Hund's$ rule.
