Mark should inform the Scrum Master, who can address the resource interference with the Product Owner. One of the Scrum Master's fundamental responsibilities is to maintain an environment conducive to team success and remove impediments or organizational interference that threatens Sprint execution.

Option A is incorrect because Sprint deadlines are not simply extended when resource problems occur. The Sprint is a fixed time-box. Option B is also inconsistent with self-organization because the Scrum Master should not act as a traditional manager by directly assigning Mark's task to another team member. The Scrum Team determines internally how work is allocated.

Option D incorrectly assumes that the Product Owner can automatically move unfinished work while disrupting the active Sprint. If work cannot be completed, backlog consequences are handled through the normal Sprint and backlog processes rather than by arbitrarily extending or reallocating committed work.

A mid-Sprint reassignment can undermine capacity, predictability, and Sprint commitment. The Scrum Master should therefore raise the issue with Andy and protect the team's ability to perform its committed work while facilitating an appropriate organizational resolution.
