The right answer is A (strong acid with strong base).
The reaction of an acid with a base to produce salt and water alone is called a neutralization reaction.
A salt is a compound formed following a replacement of the hydrogen ions (H +) of an acid with a basic radical during a reaction.
A normal salt is formed by the complete replacement of the H + of an acid (example Na2CO3).
while an acidic salt is formed by the incomplete replacement of the H + of an acid (eg NaHCO3).
