Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Answer
choose one answer and how it is allowed or not
I think you didn't read questions carefully. In question options asked not option so last two options are correct. The reason to be corrected of these options can be seen in solution if you have a little knowledge of LS coupling but I think you don't. Since given J value is not match to solved J values in first two options so these are incorrect while J value is match with given value in last two options so these are correct.
