Answer:

C. NaOH(s) + HCl(aaq) rightarrow NaCl(s) + H2O(aq)

Explanation:

A neutralization reaction may be defined as the reaction where an acid when it reacts with some base, the products formed are a salt and water.

Simply, we can write,

acid + base --->  salt + water

Here in option (C),

NaOH is sodium hydroxide is an base

HCl is hydrochloric acid

NaCl is sodium chloride and is the common salt

H20 is water

So, option C).  NaOH(s) + HCl(aaq) -----> NaCl(s) + H2O(aq)   is a neutralization reaction.
