Out of \( \mathrm{AgF}, \mathrm{CaF}_{2}, \mathrm{BeF}_{2} \) and \( \mathrm{MgF}_{2} \)
(a) \( \mathrm{AgF} \) and \( \mathrm{BeF}_{2} \) are insoluble, and \( \mathrm{CaF}_{2} \) and \( \mathrm{MgF}_{2} \) are soluble in water.
(b) \( \mathrm{AgF} \) and \( \mathrm{BeF}_{2} \) are soluble, and \( \mathrm{CaF}_{2} \) and \( \mathrm{MgF}_{2} \) are insoluble in water.
(c) \( \mathrm{CaF}_{2}, \mathrm{BeF}_{2}, \mathrm{MgF}_{2} \) soluble, \( \mathrm{AgF} \) is insoluble.
(d) All are insoluble
