The servant leader project manager should explore a training program that is within the project budget for the team members. This is the best option because it shows the project manager's commitment to developing the team's skills and capabilities, as well as addressing the project's needs. A training program can help the team members acquire the technical skills required for the upcoming tasks, as well as increase their motivation and confidence. This option also aligns with the servant leadership principle of "commitment to the growth of people"1.
The other options are not as effective as option D. Option A is not supportive and may demoralize the team members. Option B is not collaborative and may disrupt the team dynamics. Option C is not proactive and may damage the project manager's credibility. References: 1: PMBOKGuide, 7th edition, page 63
