The oxoacid salts of group II elements from the abov list are

Options

A. I,ii,iii,iv,v,vi
B. `I,ii,iv`
C. `iii,v,vi,
D. `ii,v,vi`

Answer

B

Explanation

The oxoacid salts of group II elements from the given list are `CaCO_(3), MgSO_(4) ` and `Sr(NO_(3))_(2)` because all salts contain acid and base with oxygen . `CaCO_(3)` is a salt of `H_(2)CO_(3)` and `Ca(OH)_(2) MgSO_(4)` is a salt of `H_(2)SO_(4)` and Mg `(OH)_(2). Sr(NO_(3))_(2)` is a salt of `HNO_(3)` and `Sr(OH)_(2)`.
