Dear Student
For de excitation of electrons the possible no
 of spectral lines are(n2-n1)(n2-n1-1)=(5-2)(5-2-1)=6Option  2 is correct
 Hope this information will clear your doubts about topic
  If you have any more doubts just ask here on the forum and our experts will try to help you out as soon as possible
