Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

One of Koch's postulates states that the pathogen must be re-isolated from the experimentally inoculated host and shown to be the same as the original pathogen. Therefore, the statement that it must not be re-isolated is incorrect.
