Solution

The correct option is A
(i),(ii), (v), (vi).

$N a_{2} S O_{4} (a q) + B a C l_{2} (a q) \to B a S O_{4} (s) + 2 N a C l (a q)$

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

The product $B a S O_{4}$ is not soluble in water, hence is a precipitate. This reaction is also called precipitation reaction due to formation of precipitate. NaCl dissolves in water.
