 same type of sublevel, but are found in different energy levels.

anonymous · Answer

3 indicates both are at same energy level. 
+1/2 indicates both have same spin. 
0 indicates that both are in same sublevel.
The difference occurs at the 2nd number which indicates that they are in different orbitals. 

So, option 1 is correct.
