Correct Answer: DThe most appropriate way for the project manager to handle the situation is to bring the team members to a meeting room. This approach not only removes the argument from a public space, which is unprofessional, but also provides a controlled environment where a structured discussion can take place. This setting allows the project manager to facilitate communication, ensure that all team members have a chance to voice their concerns, and guide the team towards a common understanding and resolution regarding the new feature and the necessary coding. This approach promotes collaboration and effective problem-solving.
