Solution

The correct option is D (b) & (d)
$B a C l_{2} (a q) + N a_{2} S O_{4} (a q) \to B a S O_{4} (s) + 2 N a C l (a q)$

The types of reactions are (b) Precipitation and (d) Double displacement.

A precipitate of $B a r i u m s u l p h a t e$ is obtained.

In double displacement reaction, two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.

So, the correct option is $D$ .
