A special single-cell organism living in a natural mineral water spring has permeabilities of 0.09, 1.00, and 0.04 for the Cl⁻, K⁺, and Na⁺ ions, respectively. Given the concentrations [Cl⁻]i = 1, [K⁺]i = 2, and [Na⁺]i = 3, what is the correct order of ion permeability?
a) K⁺ > Cl⁻ > Na⁺
b) Na⁺ > Cl⁻ > K⁺
c) Cl⁻ > Na⁺ > K⁺
d) Na⁺ > K⁺ > Cl⁺
