Hint :We know that every atom gives discontinuous line spectra and each line in the spectra corresponds to a specific wavelength and it is unique to a given element so no two elements give the same pattern of lines in their spectra.
Complete Step By Step Answer:
Line of spectrum is the light emitted consisting of a series of sharp lines. The wavelengths of the lines are characteristic of the element and may form extremely complex patterns. A spectrum defined as the assembly of energy levels in the form of radiations emitted by an atom in its excited state. We know that every atom gives discontinuous line spectra and each line in the spectra corresponds to a specific wavelength and it is unique to a given element so no two elements give the same pattern of lines in their spectra.
Different lines of spectrum represent different energy levels. That's the reason the line of spectrum of two elements is not identical.
Therefore the correct option is (C) .
Note :
In short we can say the line of the spectral line is the level of energy of an atom. Remember if we are to find the spectral lines of the same elements then they must be identical as they are the lines of the same energy level of the same element.
