A5 2
Step-by-step explanation
In Bohr series of lines of hydrogen spectrum :-
Red end means end of visible region which is balmer series of lines so n will be 2
Now for third lines with respect to Balmer series means n = (2 + 3) = 5th line
n1 = 2 and n2 = 5
For 2 5 electron will need energy to jump as 2 > 5 so no spectrum will release instead energy will be absorbed.
