Final answer:
The ethical issue in this scenario is misrepresentation, as the manager is passing off his team member's work as his own.
Step-by-step explanation:
The ethical issue in this scenario is misrepresentation because the manager is taking credit for someone else's work by presenting it as his own. Plagiarism, on the other hand, refers to presenting someone else's work as your own without giving proper credit. Conflict of interest is a situation where an individual's personal interests conflict with their professional responsibilities. Bribery involves offering or accepting something of value as a way to influence someone's decision.
