hi pls help with this question too

Answer :-
(i) When pressure is increased in the container closed filled with Hydrogen Gas.
EXPLANATION :-
We know that Temperature and Pressure play a vital role in conversion of the state.
The particles in any substance is minimum when it is solid.
In liquid it is more loosely packed than the solids.
In gases it is very loosely packed.
Now,
If we increase Pressure or Decrease Temperature, we can convert Gases to liquid and then liquids to solids.
This means particles come closer to each other when Pressure is increased or Temperature is Decreased.
Similarly,
If we want to bring particles of the Hydrogen gas in the container, we need to either increase the pressure of decrease the Temperature.
Since, we don't have any option for Decreasing Temperature, the correct option is (i)
when pressure is increased and volume is decreased then hydrogen atoms come close
