Researchers investigated the effect of urea on the three-dimensional structure of a certain enzyme. the researchers dissolved the enzyme in an aqueous buffer solution and added urea to the solution. the enzyme did not appear to have a secondary or tertiary structure. the researchers carefully removed the urea from the solution and determined that the enzyme had the original secondary and tertiary structure again.

The question as the options lacking but based on the question we can infer the ANSWER

Based on the results of the experiment we can best say that urea will disrupt the function of the certain enzyme and that when the urea is removed the enzyme regained its function.

Explanation:

Denaturation is the term used to describe urea effect on the enzymes as it inactivates it by affecting it's secondary and tertiary function. In the process it’s 3D structural conformation is altered.
