Solution -
Electrons carry negative charge while nucleus carries positive charge due to the presence of positively charged proton ions and neutral ions (which has no charge). All the electrons are attracted towards the nucleus due to its positive charge. The orbit on which an electron revolves around a nucleus has higher energy level as compared to the energy levels located in between the space of electron and nucleus.
While moving from a high energy orbital to a low energy level orbital, an electron releases some energy. Hence, in order to move closer to home, electron needs to push itself toward the nucleus by releasing energy
Hence, the given option is B
Do you have the solutions you want me to compare and contrast? :)
