Answer:
The correct answer is option C. "Confirm that the behavior has not been observed before, and then present his finding in a report".
Step-by-step explanation:
Novelty, is one of the most important features that a scientific report must have in order to be relevant. In this case, a scientist has observed a rare monkey with an odd behavior. However, the scientist is not certain that this behavior has been seen before. If the scientist wants to communicate and defend his finding, first he must confirm that the monkey's behavior is novel, and then present his finding in a scientific report.
