Answer : The correct option is, (C) 
Explanation :
Neutralization reaction : It is a type of chemical reaction in which an acid react with a base to give salt and water as a product that means it reacts to give a neutral solution.
Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.
When potassium hydroxide react with sulfuric acid then it react to give potassium sulfate (salt)and water as a product.
The balanced chemical reaction will be:

The species present on the left side of the right arrow is the reactant and the species present on the right side of the right arrow is the product.
In the balanced chemical reaction,
and
are reactants.
and
are products.
Hence, the chemical formula of the salt produced by the neutralization of potassium hydroxide with sulfuric acid is,
