The correct option is E a salt and water
When a strong acid and a strong base solution are mixed, a neutralization reaction occurs, and the products do not have characteristics of either acids or bases. Instead, a neutral salt and water are formed. This is known as neutralization reaction.
For example, HCl (strong acid) reacts with NaOH (strong base) to form NaCl (salt) and water.
HCl+NaOH→NaCl+H2O
