If n = 6, the correct sequence for filling of electrons will be

$$ns \to \left( {n - 2} \right)f \to \left( {n - 1} \right)d \to np$$

$$ns \to \left( {n - 1} \right)d \to \left( {n - 2} \right)f \to np$$

$$ns \to \left( {n - 2} \right)f \to np \to \left( {n - 1} \right)d$$

$$ns \to np\left( {n - 1} \right)d \to \left( {n - 2} \right)f$$
