Answer

Correct option: B.

Absorption line spectrum is characteristic of the element

Line respectrum is characteristic of the element because it obtained of atoms only. Continous spectrum is characteristics of the source of light.
In the spectrum of sodium, there are two prominent yellow lines of wavelength $589.0\ nm$ and $589.6\ nm.$
Absorption line spectrum is not characteristic of the element.
