According to Bohr atom model, in which of the following transitions will the frequency be maximum?

$\Delta E=13.6\left[\frac{1}{n_1^2}-\frac{1}{n_2^2}\right]=hv$

It is maximum if $n_1=1$ and $n_2=2$

$n=5\dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots ..-0.544\mathrm{eV}$

$n=4 .................................................... -0.850 \mathrm{eV}$

$n=3\dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots ..-1.511\mathrm{eV}$

$n=2\dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots -3.4\mathrm{eV}$

$n=1\dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots \dots .-13.6\mathrm{eV}$
