An acidified solution of potassium chromate was layered with an equal volume of amyl alcohol. When it was shaken after the addition of 1 mL of 3% H2O2, a blue alcohol layer was obtained. The blue colour is due to the formation of a chromium (VI) compound 'X'. What is the number of oxygen atoms bonded to chromium through only single bond in a molecule of X?

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 field, the pan with X is either deflected upwards (figure II), or deflected downwards (figure III), depending on the compound X. Identify the correct statement(s).
A
If X is H2O(l), deflection of the pan is upwards
B
If X is K4[Fe(CN)6](s), deflection of the pan is upwards.
C
If X is O2(g), deflection of the pan is downwards.
D
If X is C6H6(l), deflection of the pan is downwards
