Energy levels closer to the nucleus have lower energy than those that are far from the nucleus. When an electron absorbs light energy, it excites from lower to higher energy levels. This electron being unstable re-emits the excess energy in the form of light and comes back to lower energy level.

Greater the energy difference between the levels, more will be the energy of photon emitted. The energy levels close to the nucleus are present far from each other, n =1 and n = 2 are present at a greater energy difference than n = 2 to n = 3. So the energy difference between n = 2 to n = 1 transition will be higher than from n = 3 to n = 2 or n = 4 to n = 2.

Hence the correct option will be level 2 to level 1
