(B) $NaCl$ imparts a golden yellow color to the Bunsen flame. This phenomenon is explained by the emission spectrum of sodium. When sodium atoms or their salts are introduced into the flame,the valence electrons absorb thermal energy and are excited to higher energy levels. When these excited electrons return to their ground state,they release the absorbed energy in the form of electromagnetic radiation in the visible region,specifically at a wavelength corresponding to the yellow color ($589.0 \ nm$ and $589.6 \ nm$).

The golden yellow colour associated with $NaCl$ in a Bunsen flame can be explained on the basis of
