FeS. Almost all metal sulfides are insoluble in water.
By the way Mg(CH3COO)2 is not Magnesium bicarbonate but Magnesium acetate, and since acetate is the conjugate ion formed from acetic acid, it enjoys relatively good solubility.
A source with general qualitative rules for the solubility of ions is given below.

FeS is insoluble in water. Metal sulphides are among the most insoluble in water.
BaCl2 is one of the few barium salts that's soluble in water. Another rule in solubility is that NH4 is always soluble in water, thus (NH4)3PO4 is soluble, it does help to identify that it's a salt between ammonia (base) and phosphoric acid(acid). For Mg(CH3COO)2, they are trying to throw you off, this is magnesium bicarbonates. Many bicarbonates are soluble in water unless carbonate.
