Ca(NO3)2 and H₂O. Option C is correct
The combination of acid and base to form salt and water at the product is known as a neutralization reaction.
Hence the products of the neutralization reaction between HNO3 and Ca(OH)2 must be salt and water
From the given option, the equivalent product that are salt and water is Ca(NO3)2 and H₂O which gives the required product.
