In an experiment, $m$ grams of a compound $X$ (gas/liquid/solid) taken in a container is loaded in a balance as shown in figure I below. In the presence of a magnetic filed, the pan with $X$ is either deflected upwards (figure II), or deflected downwards (figure III), depending on the compound $X$. Identify the correct statements(s)
If $X$ is $H _{2} O (l)$, deflection of the pan is upwards.
If $X$ is $K _{4}\left[ Fe ( CN )_{6}\right]$ (s), deflection of the pan is upwards.
If $X$ is $O _{2}(g)$, deflection of the pan is downwards.
If $X$ is $C _{6} H _{6}(I)$, deflection of the pan is downwards.

The Correct Option isA, B, C
Solution and Explanation
(A) If $X$ is $H _{2} O (l)$, deflection of the pan is upwards. (B) If $X$ is $K _{4}\left[ Fe ( CN )_{6}\right]$ (s), deflection of the pan is upwards. (C) If $X$ is $O _{2}(g)$, deflection of the pan is downwards.
