Solution

The correct option is A i, ii, iv, v
$N a_{2} S O_{4} (a q) + B a C l_{2} (a q) \to B a S O_{4} (s) + 2 N a C l (a q)$

In above reaction, $N a^{+}$ and $B a^{2 +}$ ions are exchanged between the reactants, hence it is a double displacement reaction.

The product barium sulphate $({BaSO}_{4}$ ) is not soluble in water and hence, is a precipitate. This reaction is also called precipitation reaction due to formation of precipitate.

The other product, sodium chloride $(NaCl)$ dissolves in water.
