Answer:
The enzyme has an activity level of 3 (option A)
Step-by-step explanation:
To evaluate the enzyme activity you might observe the amounts of starch remaining in a solution or the enzyme activity. Both of them can be done qualitatively by adding substances such as iodine to the sample, which will express, through different degrees of the blue color, the enzyme activity level. So,
no enzymatic activity ----------------> level 0
low enzymatic activity ---------------> level 1
moderate enzymatic activity ------> level 2
High enzymatic activity --------------> level 3
In the exposed example there is a strong amylase activity, breaking down starch, which means that there is a very low level of starch and high level of enzymatic activity.
