  2. n = 3 , l = 0 , m = 0 , s = + 1/ 2 .

  3. n = 3 , l = 1 , m = 1 , s = + 1/ 2 .

  4. n = 3 , l = 2 , m = 1 , s = + 1/ 2 .

D Correct answer
Explanation

this option is incorrect because , according to n+l rule , highest energy is possesed by that set which has highest value of n + l . so , in this case , n = 3 , l = 2 . hence n+l = 5 . which is not the highest among the options . hence this option is incorrect .
