Explanation:
In this experiment catalase acts as the catalyzing enzyme which decomposes hydrogen peroxide. All living things (be it frozen liver or a potato) consists of catalase. Such enzymes decompose one substance into another. Catalase enzyme helps in breaking down hydrogen peroxide into water and oxygen and also speed up the process of decomposition by providing and maintaining favorable situation. Therefore, irrespective of whether this catalase is found in the frozen liver or potato, they would react in the similar manner.
Hence, option A is correct
