The figure indicates the enegry level diagram of an atom and the origin of six spectral lines in emission (e.g. line no.`5` series from the transition from level `B` to `A`). The following spectral lines will also occur in the absorption spectrum

Options

A. `1, 4, 6`
B. `4, 5, 6`
C. `1, 2, 3`
D. `1, 2, 3, 4, 5, 6`

Answer

C

Explanation

The absorption lines are obtained when the electron jumps from ground state `(n = 1)` to the higher energy states. Thus only `1, 2` and `3` lines will be obtained.
