Answer: Option (4) is the correct answer.
Explanation:
When sulfuric acid reacts with calcium hydroxide then it results in the formation of calcium sulfate and water.
The chemical reaction for the same will be as follows.
[tex]H_{2}SO_{4} + Ca(OH)_{2} \rightarrow CaSO_{4} + 2H_{2}O[/tex]
Thus, we can conclude that [tex]CaSO_{4}[/tex] salt is produced when sulfuric acid and calcium hydroxide react completely.
