In an experiment, $\mathrm{m}$ grams of a compound $\mathrm{X}$ (gas/liquid/solid) taken in a container is loaded in a balance as shown in figure $\mathrm{I}$ below. In the presence of a magnetic field, the pan with $\mathrm{X}$ is either deflected upwards (figure $\mathrm{II}$), or deflected downwards (figure $\mathrm{III}$), depending on the compound $\mathrm{X}$. Identify the correct statement(s).

 

1. If $\mathrm{X}$ is ${\mathrm{H}}_2\mathrm{O}\left(l\right),$ deflection of the pan is upwards.
2. If $\mathrm{X}$ is ${\mathrm{K}}_4\left[\mathrm{Fe}(\mathrm{CN}{)}_6\right]\left(\mathrm{s}\right),$ deflection of the pan is upwards.
3. If $\mathrm{X}$ ${\mathrm{O}}_2\left(\mathrm{g}\right),$deflection of the pan is downwards.
4. If $\mathrm{X}$ is ${\mathrm{C}}_6{\mathrm{H}}_6\left(l\right),$ deflection of the pan is downwards
