Given below are a few electrolytes, indicate which one among them will bring about the coagulation of a gold sol quickest and in the least of concentration?
(a) \( \mathrm{NaCl} \)
(b) \( \mathrm{MgSO}_{4} \)
(c) \( \mathrm{Al}_{2}\left(\mathrm{SO}_{4}\right)_{3} \)
(d) \( \mathrm{K}_{4}\left[\mathrm{Fe}(\mathrm{CN})_{6}\right] \)
