Answer:
Answer is: A. Vinegar and soda.
Neutralization is is reaction in which an acid (in this example vinegar or acetic acid CH₃COOH) and a base (in this example soda or some other base) react quantitatively with each other.
Balanced chemical reaction of vinegar and soda:
CH₃COOH(aq) + Na⁺(aq) → CH₃COONa(aq) + H⁺(aq).
Sodium acetate (CH₃COONa) is a salt.

- The proton carry a positive charge
- The neutron carry no electric charge (i.e electrically neutral)
- The electron carry a negative charge
