Answer:

For an electronic transition from n

2

to n

1

state, the number of lines in the spectrum are equal to

2

(n

2

−n

1

)(n

2

−n

1

+1)

Here, n

2

=5 and n

1

=2

Hence, the number of lines are equal to

2

(5−2)(5−2+1)

=6

Hence, when in a H-like sample, electrons make transition from 4

th

excited state to 2

nd

state, then 6 different spectral lines are observed.

Out of these, three lines, 5→2, 4→2 and 3→2 belong to the Balmer series.

Hence, options A and C are correct.
