A ball is made of a material of density ρ where ρoil < ρliquid = ρ < ρwater with ρoil, ρliquid and ρwater representing the densities of oil, liquid, and water, respectively. The oil, liquid, and water are immiscible. If the above ball is in equilibrium in a mixture of this oil, liquid, and water, which of the following pictures represents its equilibrium position?
