The correct option is (a) Chemical absorption

Explanation: When a strong base like aqueous sodium hydroxide is used as the absorbent to dissolve an acid gas, the absorption process is accompanied by a rapid and irreversible neutralization reaction in the liquid phase and the process is known as chemical absorption or reactive absorption.
