You have a strict deadline for a report due at the end of the day. A senior colleague from another department asks if you can join an unscheduled "quick sync" to discuss a future project that isn't related to your current deadline. How should you handle this?

The most effective approach is to maintain professional boundaries while remaining collaborative. Option 'C' is the best choice because it acknowledges the colleague's request and offers a solution (scheduling a later time) while protecting the time needed for your high-priority deadline. Option 'A' demonstrates poor time management and could lead to burnout or a lower-quality report. Option 'B' can appear dismissive or rude, potentially damaging cross-departmental relationships. Option 'D' is an overreaction that creates unnecessary conflict rather than solving the immediate scheduling issue. Hence, option C.
