Answer:
B. Neutralization reaction.
Step-by-step explanation:
Acid base reaction is called neutralization reaction because the product of this reaction are neutral substances.(i.e. salt and water which are neutral in nature as their PH value is 7).
For example...
HCl + NaOH -----> NaCl + H2O
Here, acid(HCl) reacts with base(NaOH) to give nutral substances salt(NaCl) and water(H2O).
