The precipitate is the barium sulfate, or 3) BaSO4. This is because it is a solid (as seen by the (s)), unlike the other aqueous product. The fact that it is a solid means that it is insoluble in water and therefore a precipitate.

Hope this helps!

Answer: Option (3) is the correct answer.

Step-by-step explanation:

A precipitate is defined as an insoluble solid formed when two aqueous solutions chemically combine to each other.

For example,
(NH_(4))_(2)SO_(4)(aq) + Ba(NO_(3))_(2)(aq) \rightarrow BaSO_(4)(s) + 2NH_(4)NO_(3)(aq)

Since, it is known that (aq) represents aqueous and (s) represents solid. So, in this reaction barium sulphate (
BaSO_(4)) is the insoluble solid.

Hence,
BaSO_(4) is the precipitate that is formed.

Thus, we can conclude that in the given reaction
BaSO_(4) substance is the precipitate.
