Equal volume each of two sols of AgI, one obtained by adding \( \mathrm{AgNO}_{3} \) to slight excess of KI and another obtained by adding KI to slight excess of \( \mathrm{AgNO}_{3} \), are mixed together. Then:
(a) the two sols will stabilize each other
(b) the sol particles will acquire more electric charge
(c) the sols will coagulate each other mutually
(d) a true solution will be obtained
