Solution

The correct option is C continuous spectrum
Line spectra are also called atomic spectra because the lines represent wavelengths radiated from atoms when electrons change from one energy level to another.
Band spectra is the name given to groups of lines so closely spaced that each group appears to be a band
Continuous spectra: A spectrum appearing uninterrupted by lines or bands across a range of wavelengths is called continuous spectrum.
The spectrum from a black body radiation is a continuous spectrum, since it emits all wavelengths depending on the temperature of the black body
option (C) is the correct answer
