Equilibrium can be established only in closed containers.

It is not possible for an equilibrium to be established in an open container as the products of the reaction of the components of the equilibrium can escape out into the atmosphere.

Hence, out of the given options, equilibrium can only be established in the balloon between water droplets and water vapors.

Therefore, Option (2) is correct.
