    A)                 \[n=4,\,l=0,\,m=0,\,s=+\frac{1}{2}\]

    B)                 \[n=3,\,l=0,\,m=0,\,s=+\frac{1}{2}\]

    C)                 \[n=3,\,l=1,\,m=1,\,s=+\frac{1}{2}\]

    D)                 \[n=3,\,l=2,\,m=1,\,s=+\frac{1}{2}\]

    Correct Answer: D

    Solution :

                    Orbitals are \[4s,\,\,3s,\,\,3p\] and \[3d\]. Out of these 3d has highest energy.
