Correct Answer: BIn a project with strict time constraints, arranging formal training sessions may not be the most efficient use of time, as it requires additional planning, organization, and potentially downtime for the team member to attend. On the other hand, pairing the team member with an experienced colleague allows for immediate, hands-on learning through direct interaction with the project work. This method provides the team member with practical, on-the-job training, allowing them to learn and contribute simultaneously, thereby minimizing the productivity impact and ensuring the project stays on track. This approach also leverages the existing knowledge within the team and fosters collaboration.
