Bohr model is a system consisting of small, dense nucleus surounded by orbting electrons. The electrons travel in defined circular orbits around the nucleus for which orbital angular momentum is an itnegral multiple of `h/(2pi)`. While rotating in allowed orbits the electrons does not raidate energy. Electromagneitc radiations are emitted when the electrons jumps from a higher orbit `(E_(n_i))` to a lower orbit `(E_(n_f))`
When an electron jumps from higher to lower orbit energy is:

Options

A. emitted
B. absorbed
C. zero
D. infinite
