During a project, a team member approaches the project manager and admits they lack the skills to complete a assigned technical task, which is on the critical path. What should the project manager do FIRST?

Reassign the task to a more senior team member immediately to protect the schedule.

Send the team member to external training and pause the task until they return.

Note the lack of skills in the team member's performance review.

Pair the team member with a senior expert to complete the task together (Pair Programming/Mentoring).
