The electron in a hydrogen atom in a sample is in the $n^{th}$ excited state. The number of different spectral lines obtained in its emission spectrum will be:
- A$1 + 2 + 3 + \dots + (n - 1)$
- B$1 + 2 + 3 + \dots + n$
- C$1 + 2 + 3 + \dots + (n + 1)$
- D$1 \times 2 \times 3 \times \dots \times (n - 1)$
