Figure shows the enegry levels `P, Q, R, S` and `G` of an atom where `G` is the ground state. A red line in the emission spectrum of the atom can be obtaned by an energy level change from `Q` so `S`. A blue line can be obtained by following energy level change

But colours are only visible if the jump is in the limit of balmer series, as per ur solution you jumped into lymer in which any colour isn't gonna be visible. Doesn't that make the actual answer is R to S.
