1. The problem statement, all variables and given/known data

2. Relevant equations

3. The attempt at a solution

$E \propto n^2$

$\frac { \Delta E} E = \frac { 2n +1} {n^2}$

In the limit of large quantum number, $\frac { \Delta E} E = \frac { 2} {n}$, option (a).

That is probably the answer they are looking for. Perhaps there is a case for d). The question is phrased very sloppily.
