The solubility of three compounds in water is shown in the table above. What best explains the observations shown in the table?

A. Lead (II) fluoride is most soluble because the ions are held together by weak attractive forces.
B. Lead (1) iodide is partially soluble in water because the lead ions are attracted to the hydrogen ions in water.
C. Lead (II) hydroxide is least soluble because this is a molecular compound held together by strong covalent bonds.
D. Lead (ID) hydroxide is least soluble because the hydroxide ions in water decrease the dissociation of the ions due to the common ion effect.
