Detailed Solution

Concept- The emission spectrum, which consists of distinct lines, is produced by observing and documenting the wavelengths of the released photons. Additionally, the lines in the hydrogen emission spectrum are categorised into a variety of series. Additionally, each of these series corresponds to the excited electrons descending to a certain energy level.
For n1=1 Lyman series
n1= 2 Balmer series
n1= 3 Paschen series
n1= 4 Brackett series
n1= 5 Pfund series
n1=6 Humphrey series
For Humprey series, n= 6. It was first given by an American Physicist, Curtis Humprey. It states that when the electrons travel from the higher transition state where n= 7,8,9… to lower state n= 6.
According to the question, n shouldn’t be equal to 6. So, option 1, 3 and 4 are correct.
Hence, the correct answer is 2.
