Explanation

(c)
According to Bohr’s atomic model, if energy is supplied to an electron it may jump from a lower energy level to higher energy level. Energy is absorbed in the form of quanta (or photon).
$\mathrm{\Delta}E = hv$
Where, $v$ is the frequency.
According to above postulate an electron from one Bohr stationary orbit can go to next higher orbit by the absorption of electromagnetic radiation of particular frequency.
