Which of the following are correctly matched

1.	Which of the following are correctly matched
Answer» `Be(OH)_(2) lt Mg (OH)_(2) GT Ca(OH)_(2) gt Ba(OH)_(2)` [Basic strength] `Be(OH)^(2) gt Mg(OH)^(2) gt Ca (OH)^(2) lt Sr(OH)_(2)` (Thermal stability) `BeO gt MgO gt CAO gt SrO` (Basic strength) `BeSO_(4) lt SrSO_(4) lt BaSO_(4) lt CaSO_(4)` (solubility in `H_(2)O)` Solution :Basic strength of metal HYDROXIDES increases down the group II group metal. The solubility of sulphides in water decreases from Be to Ba Basic strength of II group metal oxides increase down the group
