Options

A.${MgCl}_{2},AgCl$ and ${AlCl}_{3}$
B.$AgCl,{Hg}_{2}{Cl}_{2}$ and ${PbCl}_{2}$
C.${AlCl}_{3},{PbCl}_{2}$ and ${BaCl}_{2}$
D.${CuCl}_{2},AgCl$ and ${PbCl}_{2}$

Solution

${MgCl}_{2},{AlCl}_{3},{CuCl}_{2}$ are water soluble at room temperature.

$AgCl,{Hg}_{2}{Cl}_{2}$ are sparingly soluble in water ${PbCl}_{2}$ is soluble in hot water.
