Solution

The correct options are
A $h_{2} > h_{1}$
C $h_{1}$ should be less than the height Of corresponding liquid barometer
Now, let the atmospheric pressure at the end of $h_{2}$ side is $P_{a} t m$
So, $P_{a t m} + ρ g h_{2} = ρ g h_{1}$
So, $ρ g h_{2} > ρ g h_{1}$
$∴ h_{2} > h_{1}$
Basically here $h_{2}$ is a liquid barometer

The correct answer is $A$ and $C$
