In H spectrum electron moves from 5th orbit to 2nd orbit in multi step then total number of lines in infrared region and ultravoilet region respectively are :

1) 3,0

2) 3,1

3) 5,0

4) 4,0

Dear student,
In H spectrum, the infrared line is when the electron dropped to 3^rd orbital so from 5^th to 3^rd is possible via three way 5 to 4 and then 4 to 5 or directly 5 to 3.
For ultraviolet region the electron is dropped to first orbital
which is not possible in the given question.
Therefore, the answer is 1)
