Well, $(b)$ $(b)$ , and $(c)$ $(c)$ , and $(f)$ $(f)$ to a first approx...

Explanation:

Chromic oxide, and $M o S_{2}$ $MoS_2$ , and $H g I_{2}$ $HgI_2$ are all as soluble as bricks in aqueous phases. On the other hand, $A s C l_{3}$ $AsCl_3$ , the old so-called $butter of arsenic$ $"butter of arsenic"$ , would swiftly react with water according to the following equation..

$A s C l_{3} (l) + 3 H_{2} O (l) \to A s {(O H)}_{3} (a q) + 3 H C l (a q)$ $AsCl_3(l) + 3H_2O(l) rarr As(OH)_3(aq) + 3HCl(aq)$

$P b {(N O_{3})}_{2}$ $Pb(NO_3)_2$ speciates in aqueous solution to give stoichiometric $P b^{2 +}$ $Pb^(2+)$ and $N O_{3}^{-}$ $NO_3^(-)$ . Note that MOST nitrate salts are water soluble...given that the anion is not very charge dense.

Sodium metavanadate, $N a^{+} V O_{3}^{-}$ $Na^+VO_3^(-)$ would have some considerable water solubility. Did I get them all?
